Template pins are being deleted too quickly

The templates T1, T2, and T3 are currently being deleted very quickly. As soon as the program appears to close, the templates may already be gone.

I would like to see the templates saved for much longer. They can stay there until they’re overwritten.

It would also be cool if the templates could then be transferred to another project. Just like photos, the datasets could simply be deleted if they don’t exist in the other project.
