* pull out network indicator logic

* rename callbacks

* re-execute on reconnection

* make sure tool bar is disabled on start up

* clean up

* node safety

* disable toolbar buttons properly

* grey scale action icon icons dodgy

* test tweaks

* Revert "grey scale action icon icons dodgy"

This reverts commit c3d12a0f05.
