Support popup mode for sidebar panes

[fuweichin]

Type: Feature Request

To give room to code editors, especially when comparing files or opening two files side-by-side, currently I would hide sidebar panes (Explorer, Search, ..., Extensions), the problem is I need to hide them frequently and it bothers.

An extension named Auto Hide can partially solve the problem, but it cause movement / flickering to editor tabs. In Visual Studio, there is "Auto Hide" feature for view panels, and that doesn't cause movement / flickering to editor tabs.

So, I request a similar feature for Visual Studio Code: popup mode for sidebar panes.

In popup mode,

• sidebar panes will show over editor tabs, instead of showing aside editor tabs
• toggle of sidebar panes can be optionally triggered by mouseenter/mouselease, in addition to default click/blur

Thus, related settings may be like this:

{
  "workbench.sideBar.workingMode": "tab", // or "popup", "popup-hover"
}
