Frequently used hashtags can be easily added to posts.
Edit
Tags can be listed and registered in advance, and tags included in posts are automatically registered.
Multiple tags can be grouped together and added to a post at once.
Input Support
The "#" hashtag and "@" mentions can be easily entered from the keyboard.
If you enter a hashtag directly, it will be suggested by frequency of use from among the registered ones.
Mention input is suggested in the same way. This is done using bluesky's API.
