List of suggestion about improving UI

[gorfist]

I am using grin++ since 2019, and I saw that improving a lot in UI/UX and other parameters in the last two years. I decided to list suggestions that came to my mind about improving UI/UX. However, I'm not an expert, and some of these suggestions may risk users' security.

1-

I think a button for copying text is missing here. I don't know it is possible to send the slatepack message in QR code form, but it's helpful to remove the barrier of copying & pasting it.
2-

After pasting the address, it's good to have a cross sign to delete entered address IMO.
3-

Since canceled transactions could be done for testing by users, the history will not be needed anymore, and there should be a button for deleting them arbitrarily. If I think aggressively, this could be done with sent transactions as well, with confirmation modal.
4-

Non-English speakers face trouble in first use most of the time, so it's better to have this part considered in public/locales/ to get translated as well.
5-

Copy and paste icons can place in slatepack message and response box.
