Trills, Tremolos, and Glissandos

Finale, and most likely Sibeluis too, can play these, so why can't MuseScore do it too? I, and most likely most other people, don't want to spend money on those notation softwares just to get those features.

I really don't want to go into this, but by definition, trills are two adjacent notes that rapidly alternate with each other, while tremolos are two or more notes alternating rapidly. A glissando is a slide across the keyboard from note A to note B. Yes, everyone has different ways of playing each of these, but that doesn't mean you can't add them as a feature! Then Finale and Sibelius shouldn't have added them either! If they are added, couldn't they just be customized according to the tempo or how the user wants it?

And also, if MuseScore can't play trills, tremolos, and glissandos, shouldn't it not be able to play rolled chords as well? It seems to do a good job playing those, even if everyone has different ways of playing them too. Why not have MuseScore play those three missing elements of music using the same concept?

MuseScore not playing these is actually, in my opinion, counter-intuitive, because it not only limits our creativity of writing music (since many musical pieces use them), but it just doesn't sound right when you want to hear a trill/tremolo/glissando after you write the music and you can't hear it due to the missing features.

Please hear me out on this. Music needs articulations like these. How would Chopin have liked it if no one played the trills he wrote in his Nocturne op. 9, no. 2, simply because everyone interprets them differently? Or take Beethoven's third movement of Moonlight sonata. How would he feel if no one played his tremolos in that piece (which contains lots of them), provided that he could hear?
