Add php runtime to allow running php scripts locally.  I have kodiak installed on my ipad which does just that. Textastic could benefit. 

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

Similar to Sublime Text, it would be awesome if when you typed it would suggest/ autocomplete based on other words in the current document. 

Now that Working Copy has built-in Elm syntax highlighting, I’ve stopped using Textastic. The instructions for installing external syntax highlighting is weak (including in the PDF). Even if we could just point to a Github repository for a .tmbundle, it seems that the Elm versions assume elm-format to be installed, which makes them incompatible with Textastic on iPad and iPhone.

a lot of file extensions are not associated or having the option to open them with textastic app using Files/iCloud/OneDrive/etc..

Please add the ability to edit any text based file extension from there.

When I add a new FTP I'd like to be able to use 1Password.

Have the ability to select multiple parts of the document and edit it at the same time. Similar to a feature sublime text editor has.
