As long as I've been using MusicBee, custom/locked views still throw me for a loop.
For instance, say I have my Classical filter set to a custom Track Details view, but I decide I temporarily want to view my Classical filter in Artwork view. I have a couple of choices: I can edit the filter to "Default" and apply Artwork, then reconfigure the default artwork view to look the way I want for Classical. That will affect any other views using Defaut, which I probably don't want. Or I can edit the filter to "Artwork", so then when I configure it, it only affects that filter (I think?). In the first case, I can easily switch back to my custom view using the layout menu - but then, again, that switches ALL Default views. In the second case, I have to edit the filter again to switch back.
So in order not to mess up any other views, I have to edit the filter at least twice. That means right click > open filter > change > save, right click > open > change > save, rather than click > select, click > select in the layout menu. (And as much as I've messed with custom views, I'm also still not even sure I have this right.)
Maybe rather than having it in the layout menu, views could be a right click menu item for filters and playlists, so you could change them individually without having to open the whole configuration screen. (I would much rather have each filter/playlist just remember its own settings and custom views be more like static templates you can apply, but that seems to be just me.)
Edit: Or maybe better than cluttering up the right click menus more, offer a GLOBAL setting for each playlist/filter to remember its last view, rather than having to set them all to "default" if you want to switch views quickly, and then having them all change together. I'm not sure, I tend to get confused when I try to think this through. I can write convoluted library templates, but I can't seem to get my head around how the views work - which is why I think simpler is better. One thing for sure is I would like to see it work consistently between all filters, nodes, static playlists, and auto-playlists, including the main library filter.
