Currently clicking custom text inputs connected to components automatically selects all text in the field. This easily leads to accidental deletions (and ctrl-z doesn't work). Say you click your character sheet, but before you even get to editing your attention is needed elsewhere and you reflexively move with WSAD - goodbye full page of notes. Happens all the time in RPG sessions unless one is particularly careful.
My suggestion is simply to remove automatic selection of all text in component inputs, as per thread tiltle. I believe it would lead to more comfortable user experience and less wasted typing.
