Ratings and reviews

The app looks absolutely great for a relatively new IDE! I really like the UI it offers and the wide variety of languages it offers! Although, it won't let me run my C++ file and says, "Codeflash can't run that file." I don't know if that's an error on my end or just due to the app being new and still working out the kinks. Anywho, great app, and I can't wait to see what it'll become!

This looks like a very good app and is kind of unexpected actually, however, it lacks some essential feauters; there is no syntax highlighting for html nor for css, it's not possible to open files from storage, no tabs bar for opened files... But I like that it has a python compiler which is exactly what I had been looking for to exist in a small app like this one. 5 stars from me because the app looks very promising and is still new.

The GUI is really finicky, and the add file feature is also VERY BUGGY like I can't add multiple files at once and IT Doesn't USE THE FILE NAMES AND INSTEAD I HAVE TO NAME IT AGAIN!!!! WHAT THAT IS NOT USER FRIENDLY. And then the syntax highlighting is good and that's why 2 stars.
