I believe this has been discussed recently, but can't find it right now.
I'm willing to write patch, which of these features would be desirable/accepted?
1) Create user the configuration to include Lazarus version (just
major&minor) in the folder name? (at least NetBeans does this, I find
it nice :) )
2) Store what's the "default" Lazarus installation path in a setting
for that configuration and warn in case it's running the "wrong" one;
3) In the "warning" above, the allow user to chose to create a new
configuration, automatically create (and later search) based on
project folder name (if different), parent folder name and/or
arch/targetos.

Best regards,
