I like using them because you can add text onto them! When designing 2 to 4 year projects, contractors come and go [you take them up to speed by briefing, mentioning where the manual is...] but there is always some who claim not having time to read, or cannot find, the dog ate it...
Brief explanation/summary of use... on ToolPalette is in the user's face. No escaping, no BS, they cannot avoid seeing the "Help" when unfurling palettes.
On a server, there is only another guy and myself having rights to edit them.
