Nice observations, I noticed them as well…including a slight reduction in the text size in the standard detailed list view and compact list view. No bother to me as I simply notched up the zoom by 1 tick (ctrl++) but the “bolder” home and up view buttons didn’t seem obtrusive to me.
The “applications” selection in the context menu was imo redundant from the whisker menu and keyboard shortcuts. I’m glad they kept the “terminal” option in the menu because it’s super convenient to opening a terminal in the selected directory.
The one I do miss is audacious integration into the context menu. For example, right click on a (music) folder and select “play with audacious” would be nice. There might be a plugin for that already in audacious…maybe I didn’t find it yet. What I’m looking for is probably done through a Thunar “custom action” explained here – I’ll have to experiment with those items later.
