Following the github issue 1066 (https://github.com/Jermolene/TiddlyWiki5/issues/1066) and the corresponding google group https://groups.google.com/forum/#!topic/tiddlywiki/bTiOu_migHs

Goal:

Allowing to do a search in the sidebar and having the results in a tab without hiding the others and only display it when used.
