probably there won't be any more updates, but maybe I'll learn something... I'm looking for a better approach to overwriting original files with "custom" code without manipulating them myself.
I created the "myfiles" folder.
In it then myphp.php mytwig.twig and mystyle.css
An example: stylesheet.css
#menu
backgroundcolor: #ffffff;
<-- Menu End __>
@import url(/myfiles/mystyle.css);
-------------------------------------------------- ---------
mystyle.css
#menu
backgroundcolor: #bbbbbbb;
<--Menu End__> etc.
It seems logical, but I would have to do some typing with every update and I want to rule out possible sources of error (it's about 14 files where I made some code changes). Surely I could solve the whole thing with php:
<link rel="stylesheet" href="mystyle.css">
I only change one .php - the whole thing would probably be clearer.
Or have the "professionals" been smiling for a while because my way is too "woody"?.
And while we're at it, I'm playing around with version 4.0xx; I despair of just changing the colors of the navbar and the links (blue might be nice, but blue always makes me think of bluescreen

after posting i saw i am in the cloud forum, sorry. Please move it.
