Modify discardTab into discardOtherTabs and create a real discardTab

[tamwile]

This is a proposition to move the current discardTab command to a discardOtherTabs command and to use the discardTab command to discard the current tab (and switch to the next active tab).
The naming seems more appropriate.
Moreover, it seems there is no way to discard the current tab with vimium-c only ?

Any news about this ?
