Revisit selection of default payer

[jbair06]

In the previous tool, there was a default payer setting. This would allow the user to always set the default payer of a transaction. Currently, the default payer is selected based on the keys available. User feedback suggests that in cases where a user tries to create multiple transactions where the fee payer is always the same, the current default selection of fee payer can be annoying.

One suggestion was to allow the app to remember the fee payer of the last transaction created, and use that as the default fee payer for the next transaction to be created.

Another suggestion was to add the "default fee payer" setting back into the app.

If the fee payer was blank by default, that would likely be better than the current state. This would be a bit less annoying. Users like automation, when it helps with the tasks. If unhelpful, generally users would prefer no automation.

That said, both suggestions above would be automation based on user input, and therefore have value add. More feedback and brainstorming should be done.
