Inventory - Groups
Using many classes (DoW, DoM, DoH & DoL) requires having their full equipments ready in the inventory, as well as food and other items. And as you get them to a higher level, more equipments and items are needed, and you'll end up having at least 150 items (up to 200) which is kinda confusing. It's so annoying to look for the new looted piece of equipment you just got. The inventory is just messy and it might even discourage you to level a new class because you know you'll need to add more stuff to the mess.
So I'd like to suggest giving us more management options for our Inventory. Like being able to group items/equipments together and naming that group:
WAR equips / DRG equips / Mages Rings / Food / DoL items / Key items
I think that will make things much better and easier for us.
Friend List - Notes
As for the friend list, I think it's so great that we can add up to 200 players in it. But we need to be able to do more than just "add" and "remove". After playing for a year and a half, I have around 100 players in my list (after removing the inactive and unreturning ones) and the problem is that I don't remember why I added many of them, and let me explain why:
After being in an exp party, usually 2 or 3 of them tell you that (If you plan on making another party later, please let me know.) So you add them to the list for future lv.40+ exp parties.
After being in Ifrit / Moogle / Garuda fights, you befriend new people who are ready to redo the fight anytime you want.
But after a while you forget who got added for what..
We need to be able to add "Notes" to the people in our friend list, so we can put a note on each new person we add and remind ourselves why and for what we added them.
I think these two are very important and they need to be looked at.
