Trangram indeed supports basic SVG import as well as importing Trangram files (tg). To import, simply navigate to the "Import" option under the main menu (Trangram logo) in the editor.

Regarding reusing shapes or groups, you can export them as tg files and import them into your new project. This feature allows for seamless reuse across projects. I hope this clarifies things for you!

In addition to exporting/importing tg files, logged-in users can easily reuse their existing designs by directly importing them from "My Designs".
