I start this thread in order to have a place to discuss the beta release and that Hendrik receives feedback about it.
Before I begin with my impressions I must mention that I used only the Linux version on an Ubuntu based Linux distribution.
I also tested the alpha release and concerning speed I see no difference between them (although beta seems to be starting slower, could be only an impression).
Now, the issues (not all problems, some of them personal preferences) and some only impressions:
+ having a section for choosing themes with a small preview is nice, although please do not remove the Custom CSS option
+ the popup for search or formatting does not look so nice (maybe only on Linux): the rat gray is not appealing at all, the original (still present in alpha version), although was terrible in some situations because of transparency, looked nicer, more modern in a way. Maybe having a white background with some shading around borders will work better
+ in the Tag Cloud still the redundant display of tag numbers when you hover over their name
+ About Zettlr popup has the strange tag dialog.about.contributors, I think it should be only Contributors (as I side note, not all the contributions are mentioned...)
For the moment is all that I discovered.
As a side note (if it is necessary I'll opened an Issue) in the sidebar I would like that if I have a folder selected (with subfolders) in Directories section in the file sidebar it will be nice that the subfolders display their files only when selected, otherwise it is difficult to navigate if you have a lot of files in them.
Later edit: I thought that Markdown is supported in posting here :)
