I’m talking about a mode that changes based on your current system night/light , and whether there is an option to acitvate dark mode manually
so far i couldnt find it. i am able to change colors manually, but that means i have to change every color and tune them, not just the background. and when i switch to light mode again, i have to change every color and bubble again
Once set to Dark Mode for the menus using File → Options → General → Dark Mode…
Open the Inspector (Ctrl+Shift+I).
Choose Document Settings.
Select Background Colour, setting it to Black (or any variant) from the colour pallet.
Your text automatically inverts its colour from black (well default actually) to white (again, the default).
Colour text and connectors is a matter of preference after that.
Oh, and prints outs to PDF (and I assume paper–don’t use the stuff), regard the diagram as having been created in light mode.
The only caveat is you need to set the background for each Scapple diagram you create.
