You can sell your items to discard them.

Also, I suggest you to not collect subponeas until you need one, they can take a lot of space otherwise.

i know i can sell them, but i would prefer a "discard item" mod. That way i wouldnt need to be forced to wait for a store to sell unneeded or uninteresting items, or consume items i dont want to consume. The item world is great to collect new items, but since items are always unique and not stacked together, they will consume a lot of space fast, and sometimes could block the possibility to collect a good item.

You can send items to storage while in the item world, effectively dropping them for the duration of that visit. Viewing items in the inventory shows which button will send them to storage.

Now, the actual storage space is pretty small relative to the amount of loot you get, but it's plenty compared to the amount of items you'll realistically use. So unfortunately you have to manage it a bit, but there's always junk you can get rid of.

yes, i know that. i like the gameplay a lot, even without this option. maybe this is a chance to reduce "digital hoarding" while gaming.

imo the storage space is still very small if you like to manage items like a typical rpg or even diablo-like games (which always offer the option to leave behind what you dislike or find useless at some point). this is because in disgaea items arent stackable, so each will occupy a slot, and if you like collecting them to later use them for the assembly, or selling, it easy to lose track of the remaining space when fooling in the item world or hunting for new special items.

maybe, even without that option, a mod to track how many "item slots" are left could be very useful. but who knows if making something like that is too complicated.

im not a coder, but sometimes i feel i should learn a bit just to try to create this sort of options :P

I mean

If you send items to storage, they don't prevent you from getting new ones in inventory. It's no different from if you could delete them. Unless you mean drop them on the ground and make them retrievable later, that would be an entire new feature.

When you're not on a battle map the inventory and storage are functionally the same, and you can "delete" items by talking to an NPC... so yeah.

The storage limit is probably a remainder from this originally being a PS2 game, and I suspect it would be trivial to increase it if one could figure out how to mod the game to begin with. Unfortunately there's no official modding support, and the game content is just packed into two big, mean data files.

they do, if both become full, and thats the issue:
"storage space" is finite, even if bigger than "inventory space". storage will be filled automatically when picking items, but we cant know how much space is left until we visit a store, visit a "neutral zone", or return from the item world. Also, its impossible to discard items in storage: the only option is to either consume them (those who can be consumed), or sold; discarding or using items like weapons can only be done in battle with few special abilities, so that isnt a good option either if the storage became full, and we ignore it (if we get a bonus at the end of a battle, we can lose useful new items if there isnt enough space at the end).

getting a larger inventory space wouldnt be a solution, unless that change was to have something like current storage space for each item type (so it would be way harder to use all of it), and included new ways to manage groups of items by category, ie "tabs" + a "letter index" (or something like that) for each type: one storage for all swords + tab for sword type (rank#) + an option to search which specific type of sword by stat (atk spd etc). This way items could be managed in a more traditional rpg-like way, because players wouldnt be forced to be constantly selling items they collected to "harvest" specialists just to make more space: selling would be only when they wish to rather than when they need to.

Anyway, dropping useless items would be far more simple, even if an improved storage could be helpful to build soldiers and improve weapons, etc.

It's easy enough to just sell off all your junk regularly, unless you're doing a long dive into an item world and clearing all the levels without taking breaks. I haven't had an issue with the storage limit since I started seriously selling junk at every opportunity - it's not a big deal.
