Code editor
It would be nice if the codeblock Lumo uses would be an interactive code editor.
Right now if I ask Lumo to change part of my code it also tends to rewrite other parts of code which I didnt ask it to do. With an interactive code editor I would be able to select a part of the code and make a prompt just about that selected part. Or I could edit the code myself if I dont like something without having to copy paste the whole code again to Lumo to let it know I edited something. This wouldn't only make it more userfriendly but it would also be more cost efficient since it would only need to look at the selected part of code and I also wouldn't need to copy past a bunch of code into Lumo every time.
