💡Feature request: enhance topics with a shadow

see the following post:

I'm not suggesting switching back to the old editor, but having a shadow instead of just an outline is a snazzy look and gives the main topic some depth. Perhaps it could be a feature enabled with a checkbox for the main topic only: [ ] Shadow outline or something similar. It could also be useful to have this option work for standalone topics or all topics if it's easy to implement.

The current workaround is to use a light grey outline but this may not work the same with a topic color other than white. Some apps add a shadow which is a gradient shade of the color but it could be useful to have the option to change the shadow color the way the background and outline colors can be changed.

this looks really good, even if it's not the default
