+[by @lonix1](https://github.com/wekan/wekan/issues/1149)
+
+lonix1 created some css overrides with Stylish. It's not complete but I'm happy with it. I work in swimlanes mode, so that is what I changed (not list mode or calendar mode).
+
+Colors:
+- adds dark mode, I used vscode as a reference
+
+Other:
+- hides various useless icons and things
+- hides  "add card", "add swimlane", "add list" links, until hovered (I find these very "noisy")
+
