I like the ability to open all files for one language from the Files window. However, if I need to work on multiple files for different languages in one project, I would have to navigate back to the Files window to open each language. What I would like is a checkbox, similar to 'Include subfolders', but 'Include all languages', or something similar. Selecting this would allow the user to open files for all languages at once, probably each language opening in a different tab of the Editor window.
This functionality is available in Passolo, you simply select all files for all languages in the Projects tab and Open. I'd love to see something similar to this in Studio.
