is it still impossible to increase context menu entry number?
4 actual items and then "More entries"... it is really sad...
UPD. Maybe you consider adding additional option to use regular leftMouse click to open a list of recently closed tabs?
Of course the drawback would be the loss of possibility to open last closed tab via single click. However the benefit in form of full closed list seems to be reasonable.
In this way end users will be able to chose the preferable behaviour
