Hi George

I came to the same conclusion. The task is not too urgent, so we'd likely cope with it by our own means, but thanks anyway.

I should be more specific in formulating the question.
So, attempt #2:

• We used server-side source control in Studio just for having additional menu items, not for source control itself;
• Now, after switching to VSCode, we started using "normal" client-side source control based on GitLab;
• What I want is to revive those additional menu items I was able to add using Studio.

...And I don't see how to achieve it as the server-side source control menu is only active on "server-side" WorkSpaces, while client-side source control is not available there. 

I'm not sticking to this way of adding menu items to VSCode, it just seemed that it will be the easiest one.

Now I see that how wrong I was. Any idea of how to add menu items (with associated server commands) would be appreciated.

Thank you, John,

the idea is good, while I'm still unhappy and need to dig more.

Thank you all for the quick responses, but: from all the server-side source control functionality I used only the possibility to extent Studio's menu by adding items to the source control menu. E.g.

XData Menu
{
<MenuBase>
<Menu Name="%SourceMenu" Type="0">
<MenuItem Name="My item 1" Save="100"/>
<MenuItem Name="My item 2" Save="100"/>
...
</Menu>
<Menu Name="%SourceContext" Type="1">
<MenuItem Name="My item 1" Save="100"/>
<MenuItem Name="My item 2" Save="100"/>
...
</Menu>
</MenuBase>
}

Can I implement something similar with VS Code?
