About possible problems with other mods. This mod in theory won't inflict any type of conflict(outside of deinstalletion problems) as it modifies basic game values on research tab bonuses other then starting number of mechs and pilots. But in theory there might be problems with visual part of Research tab if any other mod decide to take same place in research tab grid.

Personaly, mod was designed around having bigger squads, so you aren't limited on how many mechs you have, how many pilots you have and etc. But even on vanilla squads you can have fully geared 4 teams and swap mechs and pilots when you need.

Seems an interesting mod, I haven't tried it yet but looks promising! Keep it up!
I hope squad size mod doesn't interfere much, but I am happy to know it is working fine together with your mod.
