This mod adds a tool that alows to select an area and view the combined contents of all chests in it. This provides an alternative to wiring all chests in your blue circuits stash to know how much you have accumulated.
Mod UI dissapears the moment you drop the tool. It also continiously updates in a UPS efficient way even if you select your whole base with the tool (though depending on the base size, startup lag will be noticable).
There is aslo an in game description that provides more details about how to manage the selection and which settings you can adjust.
Thank you for having a look!
