Hi Quentin,
What about a real data tools :
1) to restore old gmbrc
2) to clean the gmbrc from all old layouts (=layouts not avaliable in curents layouts) parameters ?
About 1, I can make a standalone script for that. Would you want that functionality inside gmb?
About 2, that's probably not all that hard either, but may I ask why you'd want that?
1) Yes in the "save plugin"
2) Because I often tweak layouts, and I want to know how do my layouts appear for the first time (without this function I use a temp name and I change the temp name after each change in the layout) ; because I have a lot of old layouts parameters in gmbrc I have no use.
