allready 3 tabs (knowing there's 50x more materials & items than those tabs can hold)? You must be joking. I have 10 ranks in my FC and would need 4 vault tabs at the very least to balance out its use, preferred 5 to have a seperate one for crew use (unless cells can be locked). You may not have need for them in your FC but we aim big and we love to be organized and not have to clean out the vault to make room just because members dumped too much crap in it, locking it for members that would love to make use of the better materials that no longer fit the vault due to being full. It happened to my first FC 3x in just 2 months. I suppose you are just used to less active FC's xD
