A lot of changes and improvements. Good job team! 
I was a heavy pre-release tester, but last weeks I stopped upgrading AnyType regularly, because I was afraid of data or functionality loss. By the time I have gathered quite a lot of data in my spaces and I rely on it/use it daily (both desktop and mobile). Lately, there were more serious bug reports, where AnyType was crashing/not working properly or the data was lost/messed up after upgrade and the fix was not comming several days. That scared me off. 
So I am still using AnyType Desktop 0.45.3 (and Android 0.34.21) - these are working without issues. However I dont want to be a “chicken” forever and I am thinking about upgrade to 0.46.x to check/use new features. But I need atleast one of these two “confirmations” 
:
-
My space will be not messed up after upgrade. This is maybe an optimistic assumption, because version 0.46.0 is just released (and there is already serious bug report posted) - Maybe I should wait atleast for v0.46.1 ?
-
I can safely downgrade back to 0.45.3. Means just reinstalling older version over the actual version will work? Or this is not possible, because of irreversible structure changes in objects database from 0.45.x to 0.46.x ? I will of course create backups with Export space feature and Import them back, when anything goes wrong.
