Currently, you can only use copy/paste to copy text from a code editor tab and paste it into to a terminal tab.

Textastic only supports syntax definitions and some preferences found in Sublime Packages. It does not run Python code from Sublime Packages.

I just tried to reproduce this, but it works on my iPad.

Did you maybe change the keyboard shortcut in Settings -> Keyboard Shortcuts -> File -> Upload This File? If yes, you can reset it there.

What does the overlay show when you press and hold the Cmd key on your external keyboard?

You should already see Markdown headers in the symbol list. Does this not work for you?

Yes, I know what you mean. I have already an idea for how to implement this, but would like to know what you would expect:

Should this always create a plain text file with UTF-8 encoding or should this be configurable? (for example, maybe you want a Markdown or HTML file instead).

Hello,

can you please send me such a file so I can try to find out why it doesn't use UTF-8 when opening these files (which it should)?

I can see the problem. I'll need to try if I can work around this issue on AZERTY keyboards. I'm not sure if iOS will accept Cmd-é as a valid keyboard shortcut (but it should).

You can change the scroll direction with this iOS setting: 

Settings -> General -> Trackpad & Mouse -> Natural Scrolling

Autosave cannot currently be turned off. This is the normal behavior on iOS - for example in Pages and Notes, too. A file might be opened in multiple apps or even on multiple machines when it is stored in iCloud for example, so auto save is essential to support this.

Currently, you can only hide it completely by disabling the "additional keys" setting. In the past there wasn't a reliable way (API) to check whether and external keyboard is connected. I don't know if this has changed, but it would certainly be a good feature.

Hello,

this is the default behavior in all text editing apps on iOS (e.g. Notes, Pages, any text field). It's the same as on macOS and Windows, too. To scroll, you use the scroll wheel on a mouse and a two finger drag on a trackpad.
