The Wall post box, Report in detail box and comment on answer box are annoyingly narrow, why are they this size? Any chance of making them bigger in the future?

It’s annoying when you’re using those boxes on a tablet or mobile phone. No arrow keys to scroll through what you’ve written to edit it. It isn’t fun deleting sentences in order to see the one you want to edit and then having to re-type everything or have a break from writing by opening another window and then coming back to finish you work, to find you’re at the beginning again and have to delete and rewrite the whole thing.
