+- Improve timeline UX (you can restore the original appearance by settings)
 - Remove `$[center]` MFM function
 	- This function was suddenly added last year (https://firefish.dev/firefish/firefish/-/commit/1a971efa689323d54eebb4d3646e102fb4d1d95a), but according to the [MFM spec](https://github.com/misskey-dev/mfm.js/blob/develop/docs/syntax.md#fn), `$[something]` must be an inline element (while `center` is a block element), so such a syntax is not expected by MFM renderers. Please use `<center></center>` instead.
