Two bugs with SketchUp Pro 2020 (20.2.171):
"Save As" opens a different directory when invoked using the menu versus the shortcut key. If I use command-shift-S, I am taken to the directory where I opened the current working file. If I use the menu, I am take to Documents (or presumably the default location for all models). This is almost a good thing, but the former behavior should be the default.
Scenes won’t make Untagged objects invisible. That is, if I make Untagged objects invisible and save (or resave) a scene, upon clicking on the scene in the Scenes window, Untagged becomes visible once more. This should be possible (and was in prior versions), but it doesn’t seem even remotely reasonable that this is not saveable.
