[UX] able to select "title" and "description" all at once

Title
verbose text

I hope the line between them is dotted line, or there is a button like ↗,
so that I could copy them at once and do a grammar checking on it.

Done.

Could we add something like paste all text button here?

My workflow for fixing potential typo:

1. use copy all text button
2. verify these text with external tool
3. bring fixed text back to source git

For step 3, ATM, I have to manually clear existing text, at least the title. It's not a big deal though.
