For direct integrations there is already a tool called Sublimerge (https://www.sublimerge.com/) (I am not affiliated with this team), anyone compared the two? If it's a merge tool is not integrated directly with the editor, it's not as useful.

On a side note, the competition for this sector of market, for sublime and such is much tougher, like atom and vscode being "free" to use. The one thing that hinders definitely, is the amount of third-party packages available.
