I wouldn't mind having an info tab with a textbox that would allow me to enter and save notes to a profile - things like script snippets, fine adjustments, temperature tweaks, observations and other sundry information. I currently do this with comments in the Starting Script tab, but this is asking for trouble since scripts get executed and cause errors when I forget the semicolon.
I quickly lose track of all the Profiles I've created for every scenario. Rather, I prefer to have a few filament specific profiles, and make subtle changes on a case-by-case basis. This is where a notes field would be quite handy.
