Hmm, so far it works for me as set in SEF relative format - the exact opposite of your recommendation. But I understand: neither can you be sure, nor do I doubt that non-SEF absolute is simply... safer.
I'll leave it where it's now till next update (thanks for confirming base64 issues)... saves me one hassle.
Thanks also for your comments and hints on conditions. Had not thought about practical AND/OR implementation for even only a second. Sure, that's tricky. In CBSubs you have nice conditions, and elsewhere too, but that's always only two, right? And somehow working in brackets ( ) ... oh well, can't wait to see how that would go!
REGEXP... yeah! I keep forgetting the simple things... mea culpa, and one more thanks!
