@Andreas_Hegenberg I am pleased to read that you are planning to modernize the Clipboard Manager. Since I don't know what you have in mind, I'll take the liberty of expressing a few wishes.
A kind of SnippetCenter would help me, a structure like Apple Notes. On the far left, “folders”, i.e. different sets, like the current favorites, but as many as you want to better organize the clipboards.
In the middle the “Name” and on the far right the “Editor” with the entire clipboard.
A thumbnail view would also be helpful (for me).
Maybe you have something similar in mind
