In the [TRANSPORT] bar, when the markers are also enabled :
If I (accidentally) click on the [show] action, it (correctly) opens up the window-dialogue to create new markers etc.
IF however, I want to dismiss / close this dialogue-window, I would prefer to just re-click on the [show] option again to close this window
(seeing as my mouse pointer is already right there … on the [show] widget )
At the moment the user must move the mouse pointer to another dialogue-window in order to close the (accidentally) opened window.
I think this change would make the workflow smoother (and smarter) so that the action item behaves like a toggle, no different to other widgets in the [TRANSPORT] bar.
