Enable "Open in Textastic..." prompt from within Files app for .Rmd files
When viewing a regular Markdown file in the Files app, and after selecting Textastic from the share sheet once (which sets Textastic as the default app to open Markdown files in), an "Open in Textastic..." prompt will appear in the upper right of the file preview in the Files app.
This would be great to enable for .Rmd files (and basically any other text file extension) because it would streamline my workflow of searching for a file in the iOS Spotlight, then being able to click that prompt to open the file quicker than having to go find and open Textastic first, click "Open..." and find the file.
This might be a limitation with iOS Files though, I'm not sure, because the iOS Files app displays text preview of .md files whereas it does not for .Rmd files.

Orgmode
Hello,
first thank you for this very good app. Could you perhaps consider adding org mode support?
- Syntax highlighting
- Auto-indent by header level
- Header folding
would already be very helpful.
Thank you
Kind Regards
Matthias

You can add custom syntax definitions to Textastic by using TextMate bundles or Sublime Text packages. See
https://www.textasticapp.com/v10/manual/customization/custom_syntax_themes_templates.html
This TextMate bundle should work:

SSH Port Forwarding
I started trying to use my iPad for programming purposes with server side languages (e.g. PHP). While a workflow of having to upload the files to a test server via SFTP and then reloading a browser window is doable, what I don‘t enjoy is having to have the web server be publicly available. I can use Termius to open an SSH connection and then forward the web server port to my iPad localhost. This workflow works fine, as long as I have both apps open in split screen view, otherwise Termius will drop the connection. So then I have to have the browser window in Slide Over mode, making reloading quite awkward.
Would it be possible to add the local port forwarding feature to the built in SSH client, which can already keep running together with editor windows? That would make the workflow a lot smoother, without having to have the webserver be exposed.

x-callback-url support for external folders
Current documentation shows support for local and iCloud but I wasn’t able to get this to work for external folders (I added Working Copy folder in external folders but was unable to build a url that would open a file from that location)

iOS 13: Unable to select a folder using “Open File or Folder”
On iOS 13 you can no longer select external folders in the standard UIDocumentPickerViewController
.
My proposed fix
1. Separate the “Open file or folder” button into an “Open file” button and “Open folder” button
2. Do not do anything with the “Open file” button. Everything works fine already.
3. When user taps “Open folder” button, present a document picker initialized with
UIDocumentPickerViewController(documentTypes: [kUTTypeFolder as String],
in: .open)
BTW, there’s actually a tutorial from Apple about providing access to directories here

Please support “trackpad” functionality on iPad with external keyboard to select text and navigate document
Using an iPad with a physical keyboard with Textastic is really powerful. It would become even more powerful if you can use the touchscreen as a trackpad to navigate documents and select text. This is possible in iOS 12. Check out this tweet for details.

Would love this!
This should be possible to make work when using the iOS text APIs.

Highlight current line
Similar to Sublime text, it would be awesome to have an option highlight the current line of which the cursor is on (color would be based on the theme)

Keyboard shortcut to move current selection up/down
Some text exitors have the ability to move the current line or selection up or down using the keyboard. This has many used, for reordering blocks or lines.
A number of mac apps including sublime text and omnioutliner use the shortcut cmd + ctl + up/down
