i got an idea, i recently installed the B9 aerospace pack and Firespitter, however, i'm pretty annoyed now that those mod-parts shows in the first tabs and i got to scroll all the way to the 9th tab whenever i need a structural part could it be possible to add a custom tab system? you could set up your tabs, create new tabs, arrange part order etc. maybe you could arrange that in the settings, or maybe even in the VAB/SPH also, it would be interresting if you could customise those tab differently for the VAB and SPH. also, it would be cool if you could save presets and select them inside the VAB/SPH, with one default preset (which you can't change ) this feature might not be very usefull if you are playing stock, but if you got 15 mods (200+ parts) then it might be really usefull
