This tag excerpt edit has a simple grammatical error which I wanted to correct.
I have done it by going to the excerpt and suggesting another edit, but for such minor edits the
improve button would be useful. The reviewer would then be able to correct the tag with 2 mouse clicks and in the same browser window.
When searching for this question on meta, I have found this: If I can't improve a tag wiki edit, don't show me the button -- it seems that this functionality was previously available (or was never available because of a bug). I think that it would be useful in some cases.
TL;DR I suggest adding the
improve button for tag review also.
