I have Textastic on my iPhone and my iPad. Between the two of them I have an iCloud folder that syncs files. When I create a text file on one of these devices, it will not open on the other device without a little work. Chose general category as this isn't inherently an iPhone or iPad issue. The files have the following properties:

Encoding: Unicode (UTF-8)

Line Endings: Unix (LF)

Syntax: Markdown

Below is flow of screenshots that show the issue with the Based Anarky.txt (it's a batman thing) file that originated on my iPad and I am trying to open it on my iPhone:

1. Click on greyed out file.

2. Receive error

3. Long press on file and click open as text file

4. Click open

5. Receive error, file contents not showing

6. Check file list to see file is no longer greyed out, click on file

7. File opens properly

At least in the compiler I am using now (and probably in general as I have seen this being described as an issue in some Swift forums) there must be a space before and after <= and >= (and I assume also < and >; == seem to work without in my compiler though). It would therefore be nice if the editor could automatically add a space before and after if you forget it.

This should also be part of the Prettify functionality I have just suggested.

After copying code from somewhere else or making edits not handled by auto indents it would be nice to be able to activate a prettify function to indent marked or whole file. 

It should then be possible to configure your indenting preferences.

Basic syntax support for the Crystal language. 

When I select Brave as my default browser and wish to preview an HTML file upon which I’m working, Textastic still offers only “Preview in Safari”. I suppose I can live with that: cosmetic. When I select it, however, this happens. An appropriate call to my default browser (Brave) occurs, but it yields a new blank tab, not the intended preview of a local file. Perhaps this is due to Brave’s over-protective nature. If not, it surely would be nice to be able to acquire a preview in ANY default browser.

Faster renaming of files:

(Like Pages) Click directly on the file name and you can rename the file.

Is Textastic available as a universal purchase? Currently the app store only allows using the app on both iOS (and iPadOS) and macOS through double spend. 

It would be great to have support for https://wakatime.com in Textastic. I did not find it being supported yet, so maybe it‘s something worth considering?

Please can you introduce a way to import images from other sources, such as Google Drive or the iPad's own file system. If I save an image out from (say) Photoshop at reduced quality to reduce the file size, there is no way to import it into Textastic. Correct me if I am wrong!
