I have been using the Affinity Photo & Affinity Designer betas in preference to the previous retail versions. Now that the latest retail versions have been released, I have deleted the betas but ~/Library/Containers still contains the com.seriflabs.affinitydesigner.beta & com.seriflabs.affinityphoto.beta folders with the usual Application Support, Preferences, etc. stuff.
I know some of that like the caches & aliases no longer serve any purpose & can be deleted, but I am wondering if some of the *.propcol & *.dat files might be usable as replacements for the corresponding items in the retail updates. The reason I ask is I am hoping this would (for example) set the retail macros to be the same as in the beta. That would be useful because I added a few macros to the beta that were not added to the previous retail version.
