Ability to upload .php and .js files with question

I'd love the ability to select .php files from TypingMind. Currently, it doesn't allow .php and .js files to be selected, but I can do so directly on Claude.ai.

By being able to select files, after it instructs me to make some changes to my code, I can upload it and ask if I did it correctly.

https://claude.ai/chat allows their customers to upload up to 5 files, which can include .php, .js and others.
