Change themes for static site

is it possible to change the default theme ?
or importing existing project?

Hello @zmainmd you can customise colors, logo and title of the CMS UI from the settings tab.

Regarding the import of existing projects you can duplicate a project currently: https://www.datocms.com/docs/general-concepts/transfer#duplicate-project does that help?

Might be nice to allow us to add custom css as well. There are some visuals in the editor that I think could be made simpler for my users that I dont want to create a whole plugin for, but just want to be able to add some css to override visual behavior a little. Like hiding the names of modular blocks that always have exactly one entry.
