Allow pinning hover popovers (datatips)

[timsueberkrueb]

The Atom editor had a plugin called atom-ide-ui by @facebook which supported pinning popovers that normally only show on hover.

The pinning feature allows viewing code directly next to relevant snippets of documentation.

I propose this feature for inclusion in VSCode. One possible innovation would be to automatically position those popovers on the right hand side or adding a dedicated pane where pinned popovers could be located depending on the user's current cursor position.

Alternatively, if inclusion in VSCode itself is not possible, would it technically be possible to implement this feature as an extension? Any input is appreciated. Thanks!

Hi! I'd be very interested in this feature.

It'd be pretty useful to be able to pin those tooltips for quick reference so they don't disappear, with the possibility of moving them around to place them in a convenient way, and/or resizing them.

This feature is present in Eclipse JDT, I believe I've seen it in the Resharper plugin for Visual Studio, and on JetBrain IDEs if I recall correctly, to give you a few examples.

Actually the tooltips in Eclipse/IDEA let you navigate through references in the same popup (since it's like a tiny browser) but I guess that's way beyond the scope of this request.

In any case, thank you for considering this feature.
