Why is it always red for e.g. ZOOM 100% until I pick some non-ZOOM one but orange for every other [i.e. a non-ZOOM one]?
Please check what control has focus after opening your bookmark.
Is it the search box or the bookmark sidebar?
It's possible your bookmark has an empty search.
Check your zoom bookmarks and make sure they are all single line bookmarks. (the bookmark search edit will show only one line)
If unsure, please send your %APPDATA%\Everything\Bookmarks.csv
Should not those ZOOM-ones also succumb to becoming orange?
The zoom ones should stay Red as the bookmark sidebar stays focused.
Or alternatively remain red when some other non-ZOOM one is also being active - i.e. to be shown as being active [thus in red] when also other ["normal" one] is active [shown in red]?
Or even better: should not these ZOOM-ones be shown being red only when they are clicked and still have focus / highlight on them? Because I think I finally understand how this works - and where from the confusion has come
Search commands shouldn't focus the search box.
This is important for bookmarks where you want to perform some command without changing the focus.
Ideally, you will want focus on the search box for bookmarks that change the search.
Consider adding /focus 10007 to your /zoom bookmarks.
For example:
/zoom 75
/focus 10007
This will focus the search box when you open your zoom bookmarks.
