Pre-Submission checklist

• [ ] There is no existing issue that already asks for this feature.
  
• [ ] The feature already exists in rclone (on your PC or in Termux)
• [ ] I am prepared to help make this feature

What version of Round Sync are you using (About -> App version)?

2.2.3

What problem are you trying to solve?

I have 3 recommendations...

1. You can add protection to lock the application, passcode, lock pattern, or fingerprint.

2. You can add double verification of the password when you configure a remote, or option to show password, the RCX clode version has...

3. In the remote path option, I have to write the path of the internal storage or the cloud storage.. In the RCX rclone version, it is not necessary to write the path, you can navigate and select the remote and the folder. I send you some screenshots. I speak Spanish and I am using a translator.

..

What should Round Sync be able to do differently to help with this problem?

This is requested here: #146

Hmm, maybe. I have to think about this, it is not as easy as it was in rcx. The configuration is auto-generated, and changing it might affect other configuration values aswell.

Same as suggestion 2. I have to look into it.
