Coding C++

Hi just want to say this is the best coding app for mobile but please it lacks as some very necessary applications like to create a button system clear screan but i very much love the work. Please can the be option to change the color or edit it The color should be like blueish So it can look like an AI or give it some red yellow colors just pitching an idea but i will really like it that way.

writing/editing/deleting a new line is frustrating and confusing. it will delete an entire line instead of just the TAB space and trying to put a bracket in the right place is very awkward as it seems to jump back and put it on the previous line.

This app was very good! but there's a problem, the system("cls"); or any command that has "system" on it, is not working... (Story time): I've been working on this simple Login in this app but when I put system("cls"); and run, its still working but the system("cls"); did not clear or erase the object that supposed to be removed its just says "h: cls: inaccessible or not found". But when I try to other app with similar coding its work so fine.
