I would vote against that, but that is solely based on the colour of my football teams' rivals 
Whether the source and/or destination should be red or green can already be defined in the settings (see above). BUT unfortunately a window that was originally defined as source changes AUTOMATICALLY change to a target window (with a different color), e.g. when opening a new DOPUS window. - O.K. this is a problem.
But I would like to have several(!) PREDEFINED (main) directories (e.g. C:\temp1*, C:\temp2*, C:\temp3*, C:\temp4*, C:\temp5*, C:\temp1\temp00*, C:\temp1\temp02*, C:\temp1\temp03*, C:\temp6\temp10*) FIXED "File display icons" für each DOPUS-window in several different colors (+7), which NEVER change automatically, but EVERY DOPUS-window always has exactly this ICON-color, which I have assigned to the respective window with the just mentioned specification of (each) main directory predefined.
For the beginning it would be good, if you could define under
-> Preferences -> Display -> Colors and fonts -> Other colors -> "File display icon"
with a "+"- button even MORE colors (with an own description)
as well as a deactivation button for the automatic changing of this icon color by Dopus would be present 
Hi Leo,

Do you think it is possible that you could write such a script (please) until a realization of the wish in the program itself?
Thanks in advance + Best regards
It would need a code change, since there is no way to do what you want right now even with a script.
Sounds like a good feature. +1 for developing such.

Leo, okay, I understand.
(1) Do you think that you will be able to write/implement this into source code in one of the next beta versions for testing?
(2) Until then: Can you tell me where or with which option I can deactivate the permanent AUTOMATIC switching of the (existing limited) icon colors (when changing from one open Dopus window to another, the icon colors of the Dopus windows change from "source" to "target" and vice versa), so that I have fixed (till now: two) icon colors for each opened Dopus-window?
Thx.
For (2): Preferences / Display / Colors and Fonts / File display icon
... I mean the (NOT) AUTOMATIC changing/switching of the icon colors of an dopus -» WINDOW(!) «- plz see the topic of the last messages (and not the icon colors of file display icons).
That is the same setting. Or I have no idea what you mean. 
I mean the color of this icon ...
... in the program top right:
...or in taskbar:
And at > Preferences > Display > Colors and Fonts > File display icon you can only set the colot of FILES and DIRECTORIES:
But how I wrote: If I have opened several Dopus WINDOWS the color if this icon
changes AUTOMATICALLY
depending on which window is currently "active" (by clicking on a file in one of the opened Dopus WINDOW) ... and I want to know where I can deactivate this automatic changeover.
The three colours used for the icon are set in the "Other Colors" section ("Weitere Farben" in your screenshot). In English the entry is called "File display icon" and I'm assuming in German it's "Dateianzeigesymbol".
Jon, thx. and yes ... you can set the colors here - how I already wrote in my first message of Mar 28:
-> Preferences -> Display -> Colors and fonts -> Other colors -> "File display icon"
... but until the development of the request mentioned at the beginning I would to know first, where I can DEACTIVATE the described automatic(!) changeover of the color of these icon. Thx.
Set them all to the same colour.
... and then how can I visually DIFFERENCE the contents of the individual windows on the basis of the icon color of the windows, if they get the same icon color (!-> this is the sense of my original request or these whole posts)?
You asked for "(2)" how to stop them changing automatically. That's how. Set all the icon states to the same colour and they won't change.
The other thing you ask for "(1)" isn't possible, at least not currently, as I said above.
OK, until you - maybe - make (1) it possible: Is it a lot of work for you until then (possibly in one of the next beta versions?), to integrate a button under the above-mentioned Settings, with which you can switch OFF this automatic (window) icon change => so that I can at least visually distinguish the contents of 2 open Dopus windows by the icon color (without automatic color change) with a DURABLE assignment as "Source" or "Target" (so far there are at least 2 color possibilities for the window icons at the top left: the one for "Source" and the one for "Target")?
This isn't something we're going to add any time soon.
Hi, since update to version 12.26 the icons (see e.g. the icon on the top left) of an opened DOPUS window are no longer the colors defined under Settings -> Display -> Colors and images -> File display icon, but the default icon of the respective folder selected in the DOPUS window is displayed.
How can I change it, so as it was before? Thx.
Third item in the release notes.
