[wallclockbuilder]

Description

Sending bitcoin from Bisq with a custom mining fee is impossible.
The option does not exist on the send bitcoin page.
A closer investigation shows the option exists but is hidden 2 levels deep under Preferences on the settings page.

Version

v1.5.9

Steps to reproduce

Try sending bitcoin with custom mining fees.

Expected behaviour

Custom mining fee option should be on the send bitcoin page.

Actual behaviour

Custom mining fee option does not exist on the send bitcoin page.
Custom mining fee option is actually hidden on the settings page.

Good idea. I think this would improve usability. I cannot see why it should not be implemented.

Should also be on Send BSQ when that allows user to choose sat/vb.
