Wiki pages can have pseudo-buttons, some of which allow to perform actions. For example, a link may allow editing the page. These icons are displayed at the top of the central column, aligned right. In Tiki 12, this region has a height of 19 pixels.
Starting in Tiki 13, this region no longer contains actual images by default, but rather glyphs, which increases the basic height to 20 or 21 pixels. Most importantly, a vertical padding of 12 to 16 pixels (6 px top and 6 px down for Fivealive, 8+8 in Journal) defined for .btn is added. In the end, the region's height is now between 34 and 40 pixels, which makes it more clear than before version 13 that this region uses the full column width, pushing all Wiki content by 34 to 40 pixels down.
This is of course highly inefficient, and IMO ugly. Since multilingual wikis have a language choice widget, this region can show even for unprivileged visitors.
This persists in trunk as of r60089.
I believe the region for widgets should float to the right.
If this would cause issues, or if it is too difficult to implement, we should at least override the effect of the .btn rule to eliminate vertical padding and go back to a situation close to that seen in Tiki 12.
To help developers solve the bug, we kindly request that you demonstrate your bug on a show2.tiki.org instance. To start, simply select a version and click on "Create show2.tiki.org instance". Once the instance is ready (in a minute or two), as indicated in the status window below, you can then access that instance, login (the initial admin username/password is "admin") and configure the Tiki to demonstrate your bug. Priority will be given to bugs that have been demonstrated on show2.tiki.org.
