Support vertical tabs

[tristan957]

Firefox has an extension called Tree Style Tabs, which affords the user an opportunity to have vertical tabs. I think VSCode could implement something similar extremely easily in the form of a setting window.tabLocation which could be left, right, top, bottom. In the case of left and right we could see the tabs vertically. Vertical tabs work well on smaller screens. You can normally fit more tabs vertically than you can horizontally.

Is there a reason this was listed as out-of-scope?

I would like to investigate contributing a PR for this if possible. This issue probably depends on the UI being a grid. Was that implemented yet? I run 1.39.1. If I could be pointed in a direction (which files to look at), I could definitely give it my best effort. Is there a TabContainer widget somewhere?

This is what I could come up with in a few minutes, just by changing a couple off CSS properties in the developer window

The scrollbar created at

vscode/src/vs/workbench/browser/parts/editor/tabsTitleControl.ts

Line 133 in 11f24f6

const tabsScrollbar = new ScrollableElement(scrollable, {

will also need changing. Maybe I will try out a fork and see what happens. Guidance definitely still appreciated.

Just got a new ultra-wide (32x9) monitor. Horizontal tabs are a criminal waste of precious screen real estate.
