Sort by premium when the order type is defined #2146
Description
Is your feature request related to a problem? Please describe.
The offers tab displays orders without a deterministic sorting and that makes it hard to navigate. I would expect users looking at a better premium more than anything else, then taking a look at the order terms such as bond size, or deposit time.
This is related to #1613, although the proposed change doesn't work because buy and sell orders are mixed when no order type is defined.
In that PR, it is argued that coordinators get a higher change of appearing at the top of the list based on their dev funds donation percentage as a perk, but I don't think that is too beneficial for them, because if the premium is too high (say 20% for buying) people won't even look at it. However, it does make the user experience worse.
I definitely think that coordinators donating more to the developer funds should be recognized, but using badges or other UI "boosts" would be much better.
Describe the solution you'd like
It would be great if the orders were automatically sorted by premium when selecting a BUY or SELL action.
Buy: sort by premium ASC
Sell: sort by premium DESC
Swap out: sort by premium DESC
Swap in: sort by premium ASC
Only if there was no sorting applied yet.
That way, the list is more intuitive and easier to understand, particularly for new users. Cheaper options are shown at the top and there's no need to go through the list or sort it manually.
Note
The option to change the sorting should remain as it is right now.
