txt-maker: Create .txt files

This is a text editor and notepad application that allows you to easily create .txt files, share them to PCs, write to storage, read/write files, copy to the clipboard, and send emails. It can be used as a simple plain text editor.

You can edit text boxes arranged in multiple windows (table view cells) in parallel. Furthermore, you can quickly attach and send these files via email in .txt format.

【Features】
One text file is assigned to one window, allowing you to view and edit multiple files without switching screens.
Content is automatically saved to storage each time.
Files can be exported as email attachments in .txt format.
The email button assigned to each window opens a composed email with the file attached.
Users can freely set the default subject and body of the email. This enables smooth email transmission.
