So less for Epic to do with such a gain for user (from my pov off course) :
Editor Preferences | Favorites
As in Dtails Panel with the right-click “Add to favorite”, it’d be great to get this possibility with preferences.
Amomg tremendous quqntity of parameters, as to have keyword search one by one, getting in top list “Favorite” would be so great.
Thus, parameters I spend my time to (re-)active as (eg) :
- Camera Preview
- Camera Orbit (wtf isn’t by default O___o ?)
- Unit sizes etc.
Editor Preferences | Colours (saved off course)
As to be able to right-click/add colors (little popup with colors to select),
- On lines on-demand
- Categories (putting a category in red as will put all sub-cat and lines in red…
Such a gain of visibility, that is as now for those who don’t uses one of those two functions, so why not ?
As a heigher and wider field here to write this texte (with two line heigh and scroll , becoming crazy 
)
