is it possible to have 2 different Anki Versions at the same time on the computer which syncs to the same profile? My work horse is 2.1.45 with all my fav add ons working great. Upgrading to higher Versions like 2.1.56 break a lot of add ons for me so I always have to downgrade again. Is it possible on MacOS to have 2 different Anki versions? I thought I could save my 2.1.45 in the normal applications folder like it is now and the other one in my Dropbox. Is that possible?
