When a user uploads a file to Anytype, an object is created.
If a user has previously uploaded a file to Anytype, and would like to use the same file/object as a cover or icon, they (currently) must reupload the file. If the user has deleted the original file from their device, they must download the Anytype object, and then reupload that file as a cover/icon (which just links back to the original object).
An “Objects” option when selecting an icon or cover, with the ability to search for and select already-existing [image] objects:
Any existing image is not very useful as there are a lot of small images created automatically, so now it suggests only images >= 1000px width and after playing around it works pretty well from my point of view.
