hi Mike - I'm not sure how one could object to a feature being added (or put back in, in this case) - if it's something we don't want to use, we wouldn't use it! There's a regular poster to a forum for a brand of cameras I use who gets really hot under the collar about the pop-out LCD screens on recent camera models - I think the entire forum membership has now said "hey, chill out, just don't pop the screen out".
A quick look down a list of Notes works for me - that list might already be filtered, or date-ordered, or retrieved by Tag across a number of Notebooks, or be the content of a single Notebook, or whatever; it doesn't really matter. Among other processes I'm filtering down to a point and looking for outliers which shouldn't be within that filter.
What does matter is losing around 50% of my working space because I can't switch off something I don't want to look at at that point. It especially matters because we used to be able to do it. It especially matters because the Panels in the other part of the working space (browser or app window, whatever you want to call it) can be switched on or off at will so there wouldn't seem to be a techncal reason for the non-feature.
It was Phil Libin in the Evernote Podcast more than 10 years ago who I first heard use the phrase "use case". We all have different use cases for Evernote, which I guess is why so many folk like it. It's just a shame that with v10 the EN dev team have made one of my long-standing use cases almost impossible to carry out.
