in bigger projects with multiple devices we have mixed up widgets in the tabs, so it is hard to remember which widget is associated to which hw. so, i can see in the list that there are 7 devices offline, but i do not know which widgets are actually affected.
in this scenario for example i do not know which buttons will actually have imediate effect (online) and which ones are offline.
this feature would be generally useful for display widgets (if it is grey, the user can know that it displays non-relevant data), and for buttons too: even if the user change the status of a button, he is aware it will have no imediate effect on the hw, if it is grey.
it would be hard to implement this? what do you think?
