Here is a patch that I did some time ago but have never pushed out. Do you think it is an improvement when using gitk on a repo with lots of tags? Paul. [PATCH] gitk: Tag display improvements When a commit has many tags, the tag icons in the graph display can easily become so wide as to push the commit message off the right-hand edge of the graph display pane. This changes the display so that if there are more than 3 tags or they would take up more than a quarter of the width of the pane, we instead display a single tag icon with a legend inside it like "4 tags...". If the user clicks on the tag icon, gitk then displays all the tags in the diff display pane.
