Branch: refs/heads/master Author: LarsDW223 lars_paulsen@web.de Committer: LarsDW223 lars_paulsen@web.de Date: Thu, 21 Dec 2017 10:17:43 UTC Commit: da2917860f5bb059d117de1ddd36110660bc470a https://github.com/geany/geany-plugins/commit/da2917860f5bb059d117de1ddd3611...

Log Message: ----------- addons: show color tip and start Color Chooser with double click

This new feature shows a color tip if the mouse is hovered over a color value like e.g. '#fff' or '#ffffff'. If a color value is double clicked, then the Color Chooser is started. Both (showing the color tip and starting the Color Chooser) can be enabled and disabled via the plugin preferences. See #663.
