I would also like to see a submit post button in the top left.
As I'm writing this post I can see that there is an empty space on the top right of the box so one would think that the buttons could be moved down a space so that a submit button could be added in the top left.
This is especially important for people using laptops. Before the new buttons were added it was really easy for me to just slide the cursor to the top left and then tap submit. Now I have to scroll the window down to be able to hit submit adding another step to posting a message.
<i>im used to clicking the upper left submit button, i like the options but please, can you put the special options at the bottom and leave the submit msg at the top?</i>
Probably, as well as above the preview. Also going to add links to enlarge the text box.
