In CotEditor 6.2.0 and 6.2.1, I updated the user guide to match Apple’s current documentation style. That said, I don’t think making a user guide “Apple-like” is necessary at all to deliver a good native app experience. So this part is really just my personal hobby.

Still, I believe it’s now probably the most Apple-like user guide among third-party apps, haha.

CotEditor 6.2.0-beta.3 is out. Added a new feature to create a multiple replace definition by importing a TSV file. (And yes, beta.2 was skipped due to a packaging mistake 😅) coteditor.com/beta

I still can’t replace my iPhone to a new one,because the size of my iPhone 13 mini is so good… I maybe buy iPhone Air within this year. But I'm not mentally prepared yet.

I'm steadily fixing issues in CotEditor 6. Sometimes I stumble upon unexpected Tahoe issues, and sometimes I find my own mistakes. After all, I often don't notice issues with setting combinations I don't use myself until release. The only way is to fix it promptly as it's found.
