Now it works fine. My installed language is English US but I do have additional keyboard layouts.
Now more feedback time.
Firs, UAC support, great that it now elevates when extracting to protected folders. Not so great that it seems to ask for UAC for all situations, even when extracting to local Documents folders for example. Also when I downloaded a zip file on Internet Explorer and chose to Open and not Save, then I chose copy from right-click menu on an item inside the archive and then pasted to a protected location, there was no UAC prompt and got an "access denied" error. I figure this may be related due to the IE temp location that is more heavily protected/sandboxed.
Minor issue/nitpick: the newly added checkboxes(thanks again) seem to be only available for Tiles view.
More desired features:
1. If/when adding checkbox support for Details view, add the checkbox to left of the "name" column that functions as a 'select all' toggle like Explorer.
2. Allow reverse sorting/arranging (sort Z to A in name for example, after clicking on Name column, and also in right-click menu add sort ascending/descending in arrange by menu)
3. This is more of a question, which I'm positive the answer is No but here goes, on Windows 8+, can the task pane be converted to a ribbon interface?
Thanks for listening to feedback.
