I tried out the “search” functionality and found it to be next to useless for my purposes.
The problem was, my experiments left me with various unwanted searches at the top of the navigator, that couldn’t be deleted.
Being a macOS programmer, I decided to investigate if there was a way to remove these and I found it!
Warning!!! This is only for the brave and experienced in manipulating .plist files
First, quit DxO.
On a Mac the location of the offending file is ~/Library/Preferences/com.dxo.PhotoLab2.plist
You need to open this in a suitable editor and look for the
searchLists key; all you need to do to get rid of all searches is to delete this key.
For those times when DxO keeps on unfolding the navigator every time you open it, even though you painstakingly closed all branches:
In the same file, look for the
APPStatusExpandedNodes key and delete all its subkeys. This will leave you with only the Favourites section unfolded to the Home level (at least that’s what happened on my computer)
From then on, you should attempt to never unfold nodes apart from under the Favourites section. The end result is that DxO opens and the navigator is usable in a couple of seconds.
Of course, all this would be unnecessary if DxO provided a simple button to clear searches and either, a “collapse all” button, or to remove expanded folders from the .plist file when they are collapsed.
