If I'm allowed to share an idea again to improve textastic, then I have maybe a very good one. the cursor wheel is very nice, but for the most situations to slow and complicated. Furthermore, it steals a lot of space on the canvas. Can you maybe implement the cursor swipe selection idea? I saw it already in codes and it is very nice and useful, specially for a text editing app like textastic. 

Here is an example : http://m.youtube.com/watch?v=6h2yrBK7MAY 

But overall again thanks for textastic ( we can't say enough thanks for this great peace of software. It is very useful for me )

When file was copy to USB DRIVE or add to ZIP using Textastic, only modified timestamp was preserved.

Please preserve possible metadata and timestamp (created ; modified ; access ; change) on file operation (copy ; move ; zip; scp ; ftp)

Add hex viewer and editor

Add Kotlin programming language

It would be great to be able to set one or more column rulers in the editor. The main issue I see with this is the handling of line wrapping in the cases where the line length is shorter than the ruler column.

Perhaps a better approach for a width-constrained editor like this would be an option to highlight lines that exceed a certain length.
