Think it'd be nicer if some stuff got their own inventory like the automaton parts get their own. While this in no way fixes our lack of storage space, it may alleviate it a bit.

Linkshells: Linkshells when used should then be added to the Linkshell menu instead of kept in inventory. From here depending on the person's authority within the shell (sackholder, etc.) the person may create new pearls, drop the pearl, switch to the pearl, or whatever normal options we have regarding pearls. The inventory pearl would be deleted and instead in our linkshell menu we'd just have our list of pearls that we've used. I know some people with multiple pearls for either socials or events and this would be a welcome addition.

Currency and seals: Ever see how we carry hundreds to millions of gil and it's all in a little text box? Why can't the other currencies be like this? I propose something similar to what I proposed for linkpearls for currency and seals. For these items, make them usable and when they are, ask for an amount to be used (for convenience) and then add it to a little text box. The current gil text box could have a drop down menu that allows to change currencies to view your current totals for what you'd like to see. Similarly, the trade and delivery box could have similar drop down menus for transferring of these items (the box menu would convert it to an item again automatically as it does with gil). Also allow for an option to re-make them into items for bazaaring purposes.

I'm sure there are situations I haven't thought off but this is just a proposal and would have to be tweaked as necessary. We need to think about different methods of alleviating our storage woes rather than just expanding the size and numbers of our bags (although I don't mind if they do so)!
