When getting to grips with DxO, one thing to remember is that, unlike most raw converters, DxO performs automatic corrections to tone, color, contrast, etc. on a per-image basis. If you do not like this starting point, you can remove all corrections (there is a preset called “no corrections” or something like that) and develop your own.
You can also customize the workspace and remove the tools that you do not use, or create multiple workspaces for individual tasks (a color and tone space, a crop and distortion space, a noise reduction space, a color grading and styling space, etc.). This will reduce clutter.
I do not use a DAM or enter keywords and that kind of thing, but you can do this within DxO. On a Mac, these labels are searchable within the Finder.
You have hit on the two things I don't like about DxO: auto correct and 'searchable'. I found the auto-correct, and shut it off. Is the Finder only available in the Elite version? I am using the free 'Essential' version 11. I'd like a LR-like "\" searchable database, if it exists.
Looks like it is a Mac-only feature.
