You can use the Recent Files list in Textastic to open recently opened external files. Different sorting of the file picker list would have to be implemented in the Working Copy file picker extension, not in Textastic.

The actual problem is that it takes a while to re-layout the file if you have auto line break enabled.

If you encounter this problem often, you might try to disable auto-line breaks in settings and set a manual line break column. Set it to a high value like 1000 to effectively disable line breaks.

The "Debug Log" setting logs client-side connections details including server answers and error codes. The log file is saved in Textastic under "Local Files" in the "logs" directory.

If you do indeed get a "login denied" error as this feedback topic suggests, then it means almost certainly that either the user name or password is wrong. The "login denied" error is displayed only if the server you are trying to connect to sends this error code.

I did use SSH tunnels in the past, so I do know what they are. I thought that you maybe just meant git over ssh, sorry for the misunderstanding.

I'm not sure what you mean. I can successfully clone repositories over SSH with Working Copy.

Did you contact Anders Borum, the author of Working Copy? Usually he is very responsive.

No, it's always binary.
