I miss being able to hit "Tab" for the pin names to appear. It would be nice for that to be added back. Unless I'm missing it.
The Tab key has been reassigned to advance the simulation by one tick while paused.
I miss it too, but maybe it could be a different key, like the grave accent key (usually next to 1 / above tab), as the tab is already in use.
This has been readded in the latest version
