@Micha thanks for respecting our forum policies 
@jpedstrand thank you for your feedback! I have filed your request to name Named Views as feature request - I don’t expect this to take very long, from my experience.
Regarding Preview Thumbs and Collapsing Menu issues - I understand your point.
Let me first propose a few workarounds.
First of all, if you know the name of the view, please notice you can simply search it using the search field at the bottom of this menu.
Next to each view in this menu, you’ll find a star symbol. By clicking this, you can mark views as favorites. This lets them show up in your Enscape interface! You’ll find an almost completely transparent lever at the right border of the Enscape window. Hover over it with your mouse, and a menu will expand, containing thumbnails of your favorite views, also allowing to move to their position immediately. Could this be a solution for these issues of yours? If not, please let me know - ideally with a brief explanation why. Thank you!
Lastly, I’ll happily file your request to save Field of View, Depth of Field etc. per view. Just let me explain why we haven’t done so, yet.
Currently, Enscape simply uses the Rhino “Named Views” objects. These exist, have a certain set of attributes, and are being saved in your Rhino project. These named views, however, don’t support features such as the ones you want us to include.
Including these features would simply mean for us to find a solution to save the Enscape views somehow on their own. Not an easy task, as Enscape does not require any save files, except for settings or camera paths. So adding these few features would mean a whole framework of new solutions we’d have to find.
Nevertheless, I’ll be happy to forward your request to our developers. However, are you aware of the fact that you can also save any number of settings presets? This way, you could for example save one settings preset per view, that might be helpful?
