I recently was working on some file transfers using filezilla, when I needed to edit a php file. Filezilla has a “view/edit” option, so I clicked it figuring, “ah, this likely won’t work, but I’ll give it a try”. To my surprize, it launched a really nice text editor, which after some research turns out to be Adobe’s Brackets. I tried this tool on Elements .mac files and on arduino .ino files, and while it reads mac files, amking external edits simple and clean, it properly color codes arduino .ino files, which is really nice.
Anyway, another tool I hope you find useful!
