Plannable v9.4: Mirror Deprecation

Important notice to users

The Chinese mirror of plannable (https://cn.plannable.org or https://plannable.gitee.io) is deprecated! We suggest all users of the mirror to use the main website (https://plannable.org) instead. As some of you may have noticed, the mirror recently may not be always up-to-date. The reason is that our Chinese hosting website (gitee.io) no longer supports re-deploying on push, that means the mirror itself will not update even if we copy the content from the main website to the mirror using a script periodically. It now requires manual update, which is hard to automate. Therefore, until further notice, we no longer recommend users to use the Chinese mirror, even thought it is usable at the moment.

Increased the margin between the time column and grid display.
