prompt area is problematic

[RogerNavelsaker]

1. Writing long prompt does not word wrap to multiple lines so cursor and text disappear off-screen (using ctrl+o editor as workaround)
2. pasting multiline text in prompt area will send on first end of line char and there by each line will be sent as seperate messages and not possible to paste multiline for editing (using ctrl+o editor as workaround)
3. up/down arrow navigation inside prompt area does not navigate lines, it goes straight to previous/next message (using ctrl+o editor as workaround)
4. newly written prompt disappear if going to previous/next message (using ctrl+o editor as workaround not possible as soon as prompt is gone it can not be recovered)
5. mouse wheel scroll will scroll first prompt area and previous/next messages, clearing it see point 4, and then scrolls the TUI. should not scroll prompt area.
