I guess this might be probably issue for that planned new version of desktop app, but maybe there would way to do it even for the current Adobe app - it would be great, if it would be possible to install Balsamiq with user rights, not admin rights (aka standalone app) - so instaled into user AppData\Local directory, not \Program Files. The same with the adobe air package - it is a problem in company enviroments, where i need to contact our Support guys for every update. And I also hate, that every day i see the info, that adobe air wants update, when i cannot update it because i am not admin.
P.S.: where will be the new non-air version (circa)? Will it support all the functions from the current one (is it somehow related, or you have to write it from scratch)?
