The Logi Options+ plus app is less intuitive than trying to use an Apple device as a lifelong Android user. 1) There's no option to bind the side buttons on my mouse to a specific keystroke (outside of creating a whole Smart Action). 2) The rear, side button is completely unusable in games because when binding an in-game action to that button, (a) It binds the action to the keystroke you've selected in the Logi app instead of the actual side button, and (b) It still doesn't register that I'm clicking the side mouse button (the front side button seems to work -sometimes-). 3) If you don't want the side mouse buttons to do anything, you have to know or look for the "Do nothing" option rather than a 'disable' or 'Nothing' option at the top of the list like any normal option menu. 4) The Logi Options app REFUSES to detect my unifying receiver, and the ONLY fix I've seen suggested online is downloading even more software (Setpoint) that was not advertised before purchasing this mouse. This leads to an unstable bluetooth connection and random disconnects even during active use.
