FR: Allow user to order pools by sequence of prioritised attributes

[TerminadaPool]

In the Staking -> Pool Picker screen, would it be possible to allow the user to order pools by a selected sequence of prioritised attributes? IE: Allow the user to order by Pledge, then Cost, then Margin?

I actually had a "filter language" built in that enabled you to use json to encode your filter/sort settings, but it wasn't very user friendly:

• json isn't very approachable
• the haskell gui library's text boxes are laggy so typing your settings directly into the app was clunky

I wasn't able to come up with an easy UI for layered filtering/sorting, but it is something I would like to revisit. Perhaps other gui frameworks won't have the same issues as the haskell one the p2p-wallet is using.

What about if you had an ordering box where you could add/remove fields to/from the box and the list gets ordered accordingly? Then you could click an arrow or drag up/down the field within the box to give it higher/lower priority?

But, I don't know if the Haskell gui library has such text box features which are easily programmable.

I can give this a shot and see how involved it is. Idk if I'll be able to do the dragging (I haven't learned how to do that with this haskell library), but arrow buttons should suffice.
