I have the opposite complaint: you can't even reliably select text without also using the keyboard! Half the time I drag to select, it starts moving a block. Half the time I click to navigate, it starts a selection instead (as if I had not released the mouse from previous click). I need to press the Escape key and try again.

Notion to me is the prime example for "too much JavaScript". Opening a note in a tab take 10 seconds and interrupts me half the time with some random news or a prompt to try some AI feature.
