Install Serval and check that the Serval toolbar shows up in the GUI
Disable Serval plugin (Click Plugins -> Manage and install plugins... -> Installed and then uncheck Serval). Check that Serval toolbar disappears from GUI
Restart QGIS
Now the Serval toolbar is present in the GUI. (And the plugin is still unchecked in the plugin manager)
Steps to reproduce:
Plugins -> Manage and install plugins... -> Installed
and then uncheck Serval). Check that Serval toolbar disappears from GUIServal version: 0.8.1 QGIS version: 2.16.2 on OSX
Thank you for a very nice plugin!
