1) Yeah, fair enough. Though that does require the extra step of enabling or adjusting the status of tooltips in the settings.
2) Maybe not an issue but it is odd behaviour when 'flat view' is in the same view menu as the other views: details,list,thumbnail. Those change of views don't require a forced refresh.
3) Agreed, the shell menu will find it difficult to process these files, only mentioned in the hope you might be able to do some 'magic' on them and have it work. Easy workaround is just to assign a hotkey or toolbar application to load them, that works just fine.
