I'm adding an extra menu for editing weapon variables to make the process easier, this what my earliest prototype looks like

:
when you change a variables value (so it isn't the default anymore) it'll be highlighted in orange:

The main inspiration and a big part of the code was taken from @IceflowRE, big thank you again.

You'll have the ability to import and export custom configs for each weapon separately (see Import and Export buttons at the top), tho I still have some alignment issues there.

The upper scroll part is for general values like Name, Colour, etc. while the lower scroll part is for variables that have separate values in primary and secondary attack
