workflows: click through to filtered tasks

[oliver-sanders]

The status indicators next to each workflow contain contextual information which is revealed when you hover over it.

This feature is carried over from Cylc 7 where it was introduced as the result of a request from operators.

These indicators correspond to task state, i.e, one icon lists recently failed tasks, another lists recently succeeded ones.

Listing tasks in a tooltip is not the best way to convey this information. Perhaps a tree view with a state filter would do a better job of it as you can list the tasks, but also operate on them.

Could we add a button (or even replace the tooltip) to open a view filtered to the specified state?

If so which view would we use? Note that the "default view" will be replaced with a "default layout" in the near future.

Because we don't presently support viewing multiple workflows at the same time (issue), handing workflow hierarchies for this feature would become a little awkward.

Example:

• ~me

  • myworkflow 🟩 🟥 🟦 🟪
    • run1 🟩 🟥 🟦 🟪
    • run2 🟩 🟥 🟦 🟪

• If I click on the 🟥 next to myworkflow/run1, I would get taken to myworkflow/run1 to a view filtered for failed tasks.

• But if I click on the 🟥 next to myworkflow, what should happen?

Only have this work for workflows, and higher up the tree have a tooltip that says (e.g.) "click on the workflows below to see its failed tasks"?
