Yes, ctrl+left / right / home / end do help, but when I have a 3000 character long dictionary and I’m looking for all the instances of a word, I need either word wrap or a scrollbar (or both).
If there were a scrollbar, I could use it to scroll back and forth, and searching on the page (F3 on Chrome) would scroll to the correct position.
Sometimes I edit the text on an external text editor, then paste it in the console input field, which works, but if I then edit a little and want to copy back to the text editor for further editing, the copy doesn’t work either 
.
I did notice great improvements in the console (thank you Anvil!), but these little things are what you think about and frustrate you at every keystroke.
