In the file/folder list each alternate item has a grey background which with my failing eyes is a bit harsh, particularly with the black characters and underlining. I seems to remain the same with all the themes – is it possible to change this to something softer somewhre in the settings, or is it a hard coded feature.
File/folder lists have separated settings and are not influenced (yet) by the themes.
Open the Preferences (In the “Manage” tab of the Ribbon menu, open “Preferences” which is rightmost button. The preferences window will open).
In that window, click on “File exploration” in the left tree. Then in the body settings, uncheck “Underline folders” box. ==> that addresses the underline concern.
In the same window, in the left tree, click on “Colors”. Then in the body settings, uncheck the “Odd lines” box. ==> that addresses the alternate grey lines concern.
