SugarCRM diagnostic tool — useful for grabbing a lot of system information or, more frequently for me, just a full copy of the SugarCRM diagnostic log.
I find that I often don’t want the customdir, database dumps, md5 hashes, etc. And it takes SugarCRM a good minute or so to package all of that up and for your to download it. The process is dramatically quicker if you just select the log, but all of those checkboxes!
Works with Firefox, didn’t bother to test with anything else so far.
