    Hi,
    I'm trying to inherit the editor theme via my custom .tss file.
    I know for runtime you do the following:

    Code (CSharp):
    1.  
    2. @import url("/Assets/UI Toolkit/UnityThemes/UnityDefaultRuntimeTheme.tss");
    3.  
    4. @import url("/Assets/Code/Common/reset.uss");
    5.  
    But what's the appropriate path for the current editor theme?
    Code (CSharp):
    1.  
    2. @import url("unity-theme://what-goes-here");
    3. @import url("IOEditorBase.uss");
    4.  
    Thanks

    I personally lack experience importing theme in USS, but you may look into the ThemeRegistry class. It contains a dictionary that could help you find the path as it has changed over time.

    Can you test 
    url("unity-theme://default");
    ?

    No joy. It ends up looking like the left window, when it should look like the right:

    "unity-theme://default" is default runtime. What I need is the active editor theme like I would get from this:
    https://gyazo.com/a927d7047083835dc97385ece874e6d3

    but then I'm also importing my custom overrides

    After discussions with other devs, there is no way to import the editor theme because of multiples reasons, but everything you could do with a tss (and more) is possible with a regular stylesheet.

    alright - It's definitely a feature I think is warranted. As a tool developer: I don't want anyone to have to manaully add my necessary styles for my VisualElements on to any windows or views they create. This would lead to them likely modifying styles for my framework that should not be modified.
