When I assign left / right arrows keyboard shortcut to the side buttons above the thumb, they behave strange: When holding CMD + ALT and the mouse button (left / right to switch browser tabs for instance) I can’t keep pressing the mouse buttons - it seems to not register it after the first time. I have to let go of keyboard buttons altogether and repeat the procedure (CMD + ALT + mouse button) all together.
This worked properly in the previous version of Options app...
