Projectiles menu is longer than the height of my emacs frame on a full-hd screen... That is pretty distracting when it starts to hide part of the menubar because it grows upwards... And I think it is also easy to get lost in it.
I attached a patch as a suggestion to put things into sub menus. Maybe the order can be better, I am not yet a pro with projectile and all it has to offer.
(this is with emacs 26.3 on linux, projectile up-to-date from melpa)
