I like many of the features of this editor, but I cannot use it for grading my students' work unless it prints line numbers. I've looked through the options under "preferences," but I cannot find a way to turn on line numbers when printing. Can this feature be added?

It would be a great help when working with projects, which have make/build phase. Maybe exact error/hyperlink format can be configured in preferences. It is probably hard to run "make" command in the project directory, because of sandbox limitations, but just having error log file open in editor maybe enough. It will be refreshed after running make outside editor and clicking on error could jump to the error location.
Another scenario is editing markup files with hyperlinks and also, clicking on hyperlink could jump to another file. It could be the same feature, actually.
Thanks.

Enable again "Open in Textastic" in Finder, in 10.12.1 does'n work any more!

When developing in Python I wind up with a lot of .pyc files and occasionally a database file. I'd like the option to hide those files in the sidebar.

As stated on php.net:

echo is not actually a function (it is a language construct), so you are not required to use parentheses with it. echo (unlike some other language constructs) does not behave like a function, so it cannot always be used in the context of a function

Most code editors like Brackets, Dreamweaver and PhpStorm do not use parentheses with echo. Would be great if Textastic would do the same.

Could we have fixed width placeholders for the line and column numbers? Otherwise it gets pretty distracting.

Please add bookmarks (as in textmate) to make it easy to jump around in code and text

Please add a 'filter' option for the Folders tab. For example, I may wish to filter the view to find all files which contain 'x' in their filename,

Please add the option to choose whether results from Find are collapsed or expanded by default. Normally I just want to find whole files and not see each result within these files, but with the current implementation of Find I have to collapse all the results in order to see a clean list of files that I can work with.

Let me know,
