Add a new right-aligned "description" property to TreeItems

[eamodio]

Similar to the timestamp in the Timeline view, it would be nice to have the ability to have a string that would be rendered right-aligned for each tree item.

Maybe something like:

export class TreeItem {
    label?: string;
    description?: string | boolean;
    ...
    endDescription?: string; // or endDetails? or even just details, but that feels wrong given the other usages of details
}

@misolori This could also be used for a checkmark for pr reviews

We should first discuss this in the UI sync.

The file decoration API is also being finalized soon. We can use that for a checkmark for PR reviews too.

Current:

Example where we hide the right-aligned description on hover when the action is shown:

Example in the panel:

Seems like a fair request to me, but happy to discuss in a UX call next week.

@bpasero we actually did discuss this in last week's ux sync, seemed like everyone was in agreement of this but the specific detail of whether we hide the description label was under discussion. I personally like hiding the description on hover as that is secondary information and actions have a higher priority.

Since we are trying not to add new proposed API in October, moving to November.
