Feature description:
several of the menu items under “more actions” would feel much more accessible and usable to me, if i could assign them to these easy-to-reach locations.
i would like to have one of my corner buttons be a shortcut to track details, or to do an online/genius search, or share it, or to go to instant/radio mix based on the song, for example 
these are things that i think would feel at home one the top/bottom bar as well. (and honestly maybe even the control bar.)
Problem solved:
i keep running into unexpected limitations with customisation.
it seems like the intention is total freedom, but then not all of the options are available everywhere, and it feels arbitrary.
Brought benefits:
more flexibility, i could create what i envision 
Other application solutions:
poweramp seems to have this kind of total freedom (or so ive heard), but afaik its just a player for local files.
Additional description and context:
its very possible i just do not understand as i am not a developer. but i get if things that are dynamic and related to a particular context arent available everywhere, but many of these seem universal enough? please let me know if i am missing something. maybe it is just a lot of work?
anyhow, i am really enjoying symfonium and the new beta, it is by far my favorite music app ive ever used on android. (and maybe any platform tbh.)
thank you!
