In all tabs there is left and right arrow buttons to navigate between recently used editor elements.
But in the schematic window there is no such buttons.
After working in other editor tabs for some time you switch to schematics tab and do some things.
You then forgot where you were before and there is no left arrow button so you can not go to previous place.
If you select random tab and press left arrow button it will lead you to the schematics, so that does not solve problem.
Could you add those buttons in schematics tab too?
