First of all: I really like B4A
I would like to suggest an Auto Library Update button or Menu entry in the Editor. I find the manual update process doesn't do B4A credit. My idea is to have a XML-file ready for download (by the editor) containing the latest libraries, their versions and a marker if a registered B4A version is needed for download and install. It should be pretty easy to let the editor run through the current installed libraries and match them against those in the XML.
