"Sync kerning types from" affects source file when changes are made in target

[SCarewe]

Hello, I'm not sure this is intentional (I hope it isn't): I opened two files and started kerning in one. Somehow, the special spacing groups weren't set properly (Kern On seems not to do this anymore, odd), so I selected "Sync kerning types from...".

After syncing the kerning types (=copying them from the source file to my target file), I changed some kerning types in my target file. I switched back to my source file and found that the kerning types had also been changed there accordingly.

Is this the intended behaviour?

Hmmm... scratching my head.

This only happens if KO is running for both files. You could open both files, start KO for the target font and sync. Then close the other file.

It’s probably a bug, will have a closer look. Thanks for the notice.

It turned out to be a UI glitch. The list of special spacing groups simply did not get updated when we activate a different file (if KO is running for both files). Just fixed this.

Btw, the old special spacing groups are still available in the drop-down menu after "Sync kerning types from". I hope this is not too confusing. KO never tidies up this list (it doesn’t remove unused group names). The list of names is simply re-generated when KO starts again, based on actual usage.
