*** Newer backdrops are included in my themes now and are no longer published seperately! ***
Here are my old backdrop-sets created for DirOpus v8-12.
Note: In customize-mode please play with tile or stretch as toolbars differs in height. Also some backdrops are designed for borderless toolbars (in preferences turn borders off).
After playing a while with the settings, I think some of them are coming from W8, not from DOpus. Like bar-styles for examples. But nevertheless, thanks for your help!
Mainly border outside DO and selection (like "Standard"-view) is Win 8. Most of the GUI "within" DO is customizable (e.g. for the backdrops/toolbars borders are turned off within settings).
First, you have to add them in prefs (pictures). Then in customize mode select the toolbar you want to assign a background to, activate "picture" and select the background-file. Depending on your GUI-settings (fontsize, resolution,...) play with tile, stretch, etc. to get best results.
In prefs you may need to turn off "toolbar-border", because it will look better without.
Please note, that the backgrounds are only a small part of what you see in the previews - most work is setting the colors, but you can pick them up from the screenshots.
