Humm.. maybe an idea. I may add an option like 'Use 
current proxy for HTTPS URLs' (added on TODO list)

No need - you can use free/GPL/non free programs 
together (you can not mix their sources, but you can 
use one with another one)

I could, but there are many reasons not to do that 
(the GPL/LGPL are now the only decent open source 
licenses, other ones are generally considered as bad 
or twisted - and I don't want to switch to LGPL 
because of the risks of proprietary commercial use of 
the engine by a third party)
