Sync labels on another repository

[piotrooo]

There are any plans to add possibility to specify a repository or repositories as an input to the action which labels should be synchronized?

This could be really useful if you want to store your labels somewhere centrally and modify multiple repository labels via one action run.

New option target-repo or target-repos could be introduced.

What do you think about this feature?

Seems like a good idea! I'll try to add this as soon as I have some time. In the meanwhile, feel free to open a PR if you want to ;)
