[Feature Request] Support posting multiple toots as thread

[jbalint-de]

When creating a post with content that exceeds my instances character limit I would like to be able to split the content in multiple suitable posts that get posted as replies to the respecting previous toot as a thread.

This could be an option recommended by the UI when detecting an exceedance of the character limit of the current instance or an option able to be activated by the user by ticking a box etc.

Thanks for your work on providing the fediverse client. :tada:
