Inventory issues

Please, I'm looking forward for these issues to be fixed, the inventory, as it is now, is really uncomfortable to use.

1. Sort
It was already said by others before me, but I'll repeat it: please let us sort our items to have free slots on the same page, materials and crafting products all together.

2. Multiple selection
Please implement a multiple selection option, that allows us to delete several items all together.

3. Gear single slot
This is the most important one: please, let us put more than one gear piece in the same slot, for example: 15 "Cotton Doublet Vest of Crating" have to take 1 single slot with number "15" shown as quantity, and not 15 slots, because this makes crafters' life a lot tougher! When I level up my crafting skills with crafting leves, I craft several times the same item to complete the quest more than once in a row, but I always end up filling the inventory really soon, and I have to throw away something or complete some leves to free some slots. Having "2 Cloud Axe" instead of "Cloud Axe" and "Cloud Axe" would be a lot better.

Thank you for reading this, please fix.
