Need little more spacing under the combobox. too much spacing under address input

expanded box perhaps too big when only a few coins to select. smaller font for "use standard network address" so it fits on 2 lines.

Error message could be reduced to omit the bits before the second ]. When error is 2 lines, buttons almost outside box.
Error text persists when adding second address after successful entry.

Unable to select coins that are not enabled (optional fr: make like bestorders with fade and option to enable on click). If QTUM not enabled, I can still attempt to add a QRC-20 address, but will get a validation error.

After confirming entries, main screen shows "no registered addresses". This does not update until going to other tab (e.g. wallet) and then back.

Might be good to have sight different background for the contact address list area (example below):

Addressbook entries not visible after restarting app. Seems cause of this was wallet name existing as folder (from previous builds, folder was datestamped almost 1 year ago). Not a problem for this PR, but noting for potential future support queries.

After deleting folder, everything fine - new file created, entries visibile on subsequent starts.

I'm sure this one also occurs in the send modal or in every other part where we need to validate an address: we should make an issue to sanitize those error messages

• Spacing of form elements looks ok now.

• Search bar would be good here
  

• unable to select saved smart address from send modal

A lot of stuff related to asset network standards have been hardcoded in the frontend in several places. When we will add a new one it will not be so trivial.

This brings us to something we will need to implement in next patches: some models (e.g. coins model) in the backend are poorly designed for our current needs and some are still missing (e.g. network standard model)

Seen when clicking "edit" for a contact.
[19:51:29] [warning] [main.prerequisites.hpp:92] [2083955]: qrc:/Dex/Addressbook/AddAddressForm.qml:114:13: QML AddressTypeSelector: Binding loop detected for property "implicitHeight"

When adding coin/address entry, there is no "default selection" in dropdown (is blank)

A little overlap detected here

"Enable custom fees" text seems to have gone missing. Also happens when sending from wallet page.
