- ability to copy just value from properties window
- simplification of copied text (removal of two windows style EOLs from copied text), when using "copy this item".
- making copied text consistent - removal of additional (in relation to other tabs) spaces in Exiftool tab
It would be awesome if one could copy just value in properties dialogue, like Exif info. I don't know about the rest, but when it comes to me, I never had to copy both columns, when I need to copy something, it's always just a value.

Of course, it's not a big deal to delete it manually, but it can be a hassle, when I need to copy and paste multiple values. And two EOL characters prevent pasting an item into a single line edit box.
Now, there's the other thing. I'm not sure if it's a bug or not. If that's too unrelated, I'll make another feature suggestion. So the same dialogue and menu allows you to "Copy this item", but the format is quite... complicated and non-consistent.
This is how whitespaces/non-printable characters look, when copied from Exif tab.

I'd expect
Code: Select all
ITEM\tVALUE
Code: Select all
ITEM\tVALUE\t\r\n\r\n
Let's copy the same value from Exiftool tab:

Now it's (let's assume \s is space)
Code: Select all
ITEM\s\t\sVALUE\t\r\n\r\n
