Describe the solution you'd like
Just like how we open the airbrush, I'd like to be able to open up other tools and tweak them.
This tweaking would include

• Installing any battery we have (making battery tech automatically provide incremental improvement to tool use)
• Changing the crystal focus for Neon/Glowtite/Retium/Bioterium swords
• Ammunition for Grenade Launcher, and perhaps the power of it's throw.
• It might also allow for per-tool settings to be made, like a maximum or minimum range for the grappling slime (perhaps set by amount of slime in the tool)

Describe alternatives you've considered
A table for putting the tools in to open such a UI would be interesting.
This would make keeping upgrades to swap between nearby more intuitive, but it runs counter to the existing example of the airbrush.

If implemented in this fashion I would also request a curio for opening up the UI, to get around the need to go back to base, or carry a table around.
