This question may be related to a resolved thread.
I am still having this Tab Manager sorting issue. They seem to reorder in pretty much random ways no matter what I try.
The last comment on the above “related” thread (actually the same) is that the bug was fixed for the “next release.”
Which release is that? I am currently working with v2.1.0 Build 20100810
Tab Manager sorting bug is still alive and kicking in this version.
(And, yes, I know that the custom tabs will always follow the standard ones.)
