I can reproduce the issue with the Gmail app. Pasting the same text into Apple's Mail does give me line breaks though. I'll try to find out more.

Do you have any external folders present? Textastic is trying to list all folders when you open the select folder list. Maybe there is an external folder from a file provider that is not responding. Please try to remove external folders that you do not need or that don't work as expected.

Hello,

I'm not sure exactly where you mean. Do you have a screenshot? Is this about copying files? There is already "Duplicate" and "Copy To…".

Hello,

you can configure whether recently opened files are re-opend in Textastic's Advanced settings: "Restore files and windows when re-opening Textastic".

To show or hide the sidebar, use the View -> Show Sidebar menu or Control-Command-B.

By default, Textastic should restore files and windows from the last launch including the state of the sidebar.

Can you please give me more details? How exactly are you trying to download the files?

Textastic should be able to handle files beginning with a dot like ".htaccess".

I just downloaded a file called ".profile" using an SSH connection and could open and edit the file without problems.

It would be great if you could send me a screen recording video illustrating the problem.

If you are using an FTP connection instead of SFTP, you need to enable "Show Hidden Files" in the connection's settings. See https://www.textasticapp.com/v10/manual/remote_servers/sftp_ftps_ftp.html#configure-an-ftp-unencrypted-connection

Please show me the Markdown source code.

I'm currently working on an update of Textastic for macOS. I hope to release it within the next few weeks.
