[LAU] Audacity: not good for making loops

I guess I must have misread the Audacity web site and the manual because a moderator on the Audacity Forum just enlightened me to the fact that Audacity is NOT an audio editor (as 99.9% of the users falsely believe) but an 'Editorial Production Environment Manager'! </sarcasm> Audacity leaves *a lot* to be desired when it comes to making loops to wit: having to hit stop or pause so Audacity can 'pick up' the loop start and/or stop markers that were moved during playback makes crafting loops very painful - I'd go so far as to say useless actually. can anyone suggest an audio editor (on Linux) that edits loops in real-time? thanks in advance!
