I'm working quite a bit with b4xlibs, and it does get tiresome to switch to the Libraries Manager tab (in the project where I'm using the libs) and right-click to refresh the libraries, over and over again.
It would be nice to have an attribute like this, so it's automatic:
#RefreshLibrariesBeforeCompile
(The manual refresh would still be needed to make the IDE pick up on changes. Perhaps that also should be an option to do automatically, using the .ini?)
