Tuplets need a "Set bracket horizontal" checkbox in the Inspector

Seems like this would be relatively straightforward, we'd need to add "horizontal" as a "styled property" (so tuplets get their value from the style setting if not overridden in the Inspector).

I just got "hit" by this when trying to create the example for https://musescore.org/en/node/296893
The workaround of setting the maximum slope to 0 doesn't work (so that probably needs fixing as well). It looks like 0,05sp is the minimal required value for that setting to take effect.

"Maximum slope" is not working for me, the tuplets stay completely the same whatever value I put into it.

Re: "Maximum slope", see #280472: Tuplet brackets won't slope.

If "Maximum slope" already doesn't work in 3.0, why is this issue reported in 3.2?

Because nobody noticed it before I guess.

I actually meant this #294098, but yeah, this suggestion has little relation with maximum slope actually. And maybe this is exactly why the OP found maximum slope not statisfying: it completely doesn't work!

Likely indeed

FWIW, to me, the example looks quite good as is, and I think I would find it less attractive and even arguably harder to read if the brackets were to completely ignoring the contours. But I should say I'm less interested in a few random personal opinions than I am in statements from respected authorities on music engraving, examples from respected publishers, etc. Not that it shouldn't be supported anyhow, but it helps us prioritize the request if we understand the extent to which this is just a personal preference versus something broader.

Gould is all I have handy, and while she says it can be done optionally where it improves the look, she's pretty specific about the situations where she recommends it. And to be sure, having a checkbox rather than (just) fixing the style setting seems appropriate by this standard.

Thanks for the links! The fact that other programs provide the option is good to know, and again, I would like to see us do the same, but really only the first is especially interesting from a perspective of deciding how important the option is and whether it's advisable to actually use it. Indeed it shows one publisher explicitly preferring that in the style guide, and then a bunch of other music engravers bemoaning that saying it's a bad idea :-). Which is to say, it looks to be the stuff of religious wars, and one thing I can say about that in general, it's a subject important enough to generate such debate, it's definitely worth supporting both possibilities.

So everything I've seen so far tells me it is best to leave the defaults as they are, as this is what other programs do and what Gould recommends., but the style setting needs fixing and adding an explicit horizontal override by way of a checkbox (so you can have most tuplets slope but easily set a few explicitly horizontal as per Gould) definitely seems like a good idea.

For purposes of "frequency", in accord to the suggestion

b) Add a checkbox for "Set bracket horizontal" to force the issue on multi-selected tuplets

A conversation without a created issue was brought up about this back in 2016 when I erroneously called tuples 'tuplettes', for what it's worth: https://musescore.org/en/node/123016

I too would like to have the checkbox available :)

Many is more than 5...

Or have the "Allow diagonal" like for some orher lines, just here set to true/on by default

Oh, sorry for that.
"Allow diagonal" is a little confusing for me, as a diagonal is a line that connects two vertices. Although I've read in Wikipedia that "diagonal" is informally used to refer to any sloping line, wouldn't it be better if "Allow slope", or the opposite, "Force horizontal", was used?

Whatever term it is (going to be), it should be used consistently

Yes, I know. I've proposed the change here #310392: Replace "Allow diagonal" by "Allow slope" or the contrary "Force horizontal".
I wonder what the community thinks about it.

Us native English speakers understand what "Allow diagonal" means. There is no need for a diagonal line to be connected to anything.

Either term would work for either line type, just with different defaults

I agree with Joachim, the concept is the same - to force the line to be horizontal or to allow it to have some slope -, so the term should be the same.
I also think that the best term for the checkbox is "Force horizontal".
Why? Because in MS checkboxes are usually used to constrain behaviors, not to allow them -"small notehead", "enable autoplace", "follow staff size", etc.
In hairpins, this checkbox would be ticked by default, and in tuplet brackets, it would be unticked.

In those cases, "Always horizontal" refers to a global style setting to control all the tuplets in the score, not a setting to control the properties of individual elements.

Lines and tuplets brackets are not the same though. Lines by default are normally horizontal with few exceptions. Tuplet brackets are normally not horizontal but rather follow the slope of the beam. The check mark in both cases should tell the user that they are either selecting the normal state or unselecting the normal state regardless of which words are used. This means I think the words should be different.

Dorico clumps both "normal" lines and tuplet lines in "lines" though.

This isn't dorico or sibelius.

Here i have to disagree. It is a setting with the same meaning, just different defalts. Nither ticked nor unticked has the meaning of "normal", that is what the "reset to style" button indicates by being ebabled or disabled

This isn't dorico or sibelius.
So what?

Lines and tuplet brackets are not the same though
A straight line from the lines palette, with both 90° and 1 sp long start and end hooks, and with a width of 0.10sp, is almost exactly equal to a tuplet bracket without the number.

Why "Allow diagonal" for the first, and "Force horizontal" for the second? (I still believe that, having to choose between the two options, "Force horizontal" is better).

FWIW, Dorico had a "Can slope" property for tuplets, which was replaced with a "Force horizontal" property, because it "more closely reflects its behavior".
