Also, would it be possible for you to make this script so that it has an option for something like the non-discardable items, but have them called key items, in a different page, but have up, say, above the help box have something like, Items, or inventory or something, then, beside that something like key items, then selecting key items brings you to a different menu that would basically just be an inventory for key items that wouldn't take up the players inventory space? I know that's long and probably has a lot of errors with grammar, but I'm kinda tired and changed where I was going with it a couple of times... (just ignore that random mess, unless you feel like you absolutely must read it... the lower description is better by far.)
Sorry about it being an off-site picture, I was having some odd issues with attaching.... (This site doesn't show any recognition of it being attached? Too used to RRR lol) but I hope that explains what I mean (basically just if you label an item as a 'key item' some way [possibly an item note?] it goes under Key items, and does not take up space in the inventory whatsoever. This way your not filling up your players' inventories with a bunch of useless crap that are basically just trophies that serve no purpose other than giving players that reminiscent feeling of that one very special quest.
