Backpack and inventory

[astroHABT]

I have a little offer for (one of) next updates.
Stack loot. Sometimes textile, skin, bones, rust metal and etc. craft loot takes much more place. Why not to pack them, for example, 5pcs - 1 cell of inventory?
Too poor count of craft recipes. Why dont to make recipe - repair lighter? For exaple
Make an additional cell for ammo in players' param bookmark, with auto add, if there is such ammo in inventory. If there is no any gun in hand, the cell will be locked.
If i have any new ideas, i know, where to write
