the textbox tool is broken.
when using the text box and tapping the screen (even if using the on-screen keyboard) the textbox will undo ( and it won't be reversible ) so you will need to retype everything. furthermore, it keeps this weird overlay of way should have happened if it would work correctly or something that should have been deleted but for some reason stays. and when switching pages and then editing a textbox you will get "teleported" into a random previewed page. and if the pages are similar you might rune some notes.
