[Feature-request] Remove cursor

I would like the multi cursor to behave like this plugin - https://atom.io/packages/multi-cursor This plugin allows to remove last created cursor by adding new cursor in oposite direction. Exaple. ``` some text| some text 2 some text 3 ``` add cusor down ``` some text| some text| 2 some text 3 ``` add cursor dows ``` some text| some text| 2 some text| 3 ``` add cursor up ``` some text| some text| 2 some text 3 ``` add cursor up ``` some text| some text 2 some text 3 ``` this also works with ctrl - d command.
