im playing calamity mod with this and its pretty fun! but i noticed a couple of issues when using storage manager:

visuals: i noticed that some visuals are wrong, as if they had minimal width, or stuff being completely gone, like the scroll bar which isnt even visible but works. here's how it looks like on my game [imgur.com]
add chest mode: when adding chests, it gets tedious when you have to click add chest and a chest over and over again. i suggest an idea of shift-clicking, where if you shift-click a chest while in "add chest" mode, the mode is kept on, so you can more easily add chests.
searching: it would be nice if searching accounted for item description aswell, not just items name, like in Journey Mode.
lag: after i made a bigger storage area, from 39 to 108 chests, i notice some lag, probably due to game trying to render a lot of inventory slots in the scrolling area (including empty ones)

i hope some of this stuff get fixed, i really like this mod and it does pretty good job of adding QoL additions to the game!
