Well, since it's done...
By the way, any idea of how forcing LV to reload its menus ?
For example, I add an item in the LV help directory or projet directory and I'd like it to appear in menus without re-starting LV...
Some of the options in LV are exposed as properties, like you said.
If you want, there are also VIs in <LabVIEW>\resource\dialog\lvconfig.llb. I never really played with them (and I really don't feel the need), so I don't know if they affect the config immediately, but I think they do at least save to the INI file immediately.
As for updating, there should be refresh methods for both the palletes and the menus in the Application class, depending on your LV version, but the pallete one at least has been there for at least a few years.
thanks Tst. By the way those kind of things could be a part of the Hidden Gems library.
Regarding the refresh I saw effectively a method to refresh palettes but not menus.
