History: Sidecolumn toggle button experimenting

One of the interface changes in Tiki 25 was putting giving button classes to each of the anchor elements that contain a side column toggle icon. This was done to make the interface elements more consistent in appearance. Specifically, on wiki pages, the wikiaction dropdown icon (a vertical ellipsis icon) has a .btn-info class, and the page's edit, history, rename, etc. buttons also have Bootstrap button classes.

Also, especially on large screens, the isolated side column toggle icons, being just an icon without a surrounding button background, etc., can be quite small. So for these reasons the button classes were added. However, there was some feedback that now they look too chunky and intrusive. This discussion is the reason for this page, which will show some different arrangements of the side column toggle buttons to compare and maybe get a consensus on future versions.

Current situation (Tiki 25.0)

The buttons in this version are in the locations they've been in for many (alll?) Tiki versions: above the side columns and near the page's side margins (or content container's side margins in the case of a fixed-with layout).
