"Associated revisions" to be minimized / opened by click
Make "Associated revisions" temporarily minimized by clicking a button or a small icon. There should be some other button or icon which will be used to open "Associated revisions" again. This button/icon may be placed somewhere in the right or at other appropriate place.
Some people tend to post tables or long lines or event figures with graphics characters in "pre" areas in comments.
The long lines are wrapped to next lines and these figures get messy and unreadable. The problem gets bigger when there are associated revisions to the right of the comments that eat space.
An user accessible option to set "Associated revisions" minimized or opened by default when viewing an issue. This option may be associated to user and to an issue. Why - some user may want the "Associated revisions" closed while other may don't want. An user may want this for one issue and don't want for other issues.
