Default sidebar width should not trigger narrow mode for extensionsViewlet

[digitarald]

The default sidebar width is dynamically calculated but ends up being 251px for most window sizes I tested. The narrow mode for the extensionsViewlet is triggered for ⪬ 300px.

While narrow is great for small spaces, it hides key information like the icon, rating and download numbers. For users who don't discover the resizing, important context is lost for extensions. I noticed this during my work on getting started, as it guides users early into the extension panel; which looks no very inviting without expanded.

Ideas for solutions

• Trigger narrow for ⪬ 250px
• Add a size before narrow that allows more context like a smaller extension icon and simpler rating, or other redesign ideas.

@digitarald you are referring to the side bar, not the activity bar. See https://code.visualstudio.com/docs/getstarted/userinterface#_basic-layout and the annotated screenshot above that section.

Please update the issue.

Good observation! Strongly agree that that showing icons, the starred recommended ones, and download count would provide a richer view and catch new users' eyes.

I think your proposal is to change the default width of the sidebar (not just for the extensions view). I can't remember if @sbatten or @isidorn owns the sidebar?

[isidorn]

Please note that the SideBar probably takes the "optimal" width of the explorer since that is the initial view shown.
When we change the active view in the sidebar the sidebar does not change size. Not sure if that would be strange.

Anyways leaving this up to @sbatten to decide

I think your proposal is to change the default width of the sidebar (not just for the extensions view).

I am leaning towards the lower hanging proposal to change the min-width for narrow. For changing the default sidebar width I'd have to dig deeper into seen window sizes. I am also not aware that other panels have problems with narrow width; which would otherwise strengthen the case. The middle-ground would be increasing sidebar default width a bit and making the narrow min-width a bit wider.

@sandy081 for the narrow breakpoint in extensions viewlet

Ah, ok I see what you mean now. That makes sense to me as well, this is handled here:

vscode/src/vs/workbench/contrib/extensions/browser/extensionsViewlet.ts

Lines 564 to 572 in 17c6796

	layout(dimension: Dimension): void {
	if (this.root) {
	this.root.classList.toggle('narrow', dimension.width <= 300);
	}
	if (this.searchBox) {
	this.searchBox.layout(new Dimension(dimension.width - 34, 20));
	}
	super.layout(new Dimension(dimension.width, dimension.height - 41));
	}

And the initial default width comes from
