It is imperative that support for custom fonts be added, by selecting an existing font file on the system.

If this is not possible, please add Powerline status-patched fonts.

Can be awesome record the session on log or txt to share or get the flow to review the session history

I need to be able to use zmodem as per usual in a terminal window. Can't bother to change windows and use scp, takes too long time.
SecureCRT has zmodem support why not you? It's not hard to add.
It's much faster to use "sz blah.zip" from a terminal instead of alt tab or create new window and do scp or whatever.

Add the ability to use an external editor through SFTP menu (WinSCP style). This would allow for the configuration of editors like Atom or Notepad++ without having to transfer back and forth.

I use a master password solution that stores my 2FA authentication and I'd rather not be required to use Authy for one app (this one).

Or at least make a brighter cursor for the "Pro" scheme. Dark gray is close to invisible.

It looks like you can either save Termius your ssh key’s passphrase and it will remember it forever (which seems to defeat the passphrase entirely), or you don’t tell it your passphrase and you’re prompted every time you connect.

It would be good to have Termius prompt once, and remember it for the rest of the session, or day, or some fixed time period (and perhaps a button to forget it explicitly).

It'd be great if you could add support for OpenKeyChain which is a PGP key manager. It supports hardware tokens (OpenPGP cards or yubikeys with OpenPGP java Applet) through NFC. It would be great to be able to use these for key based login. I already use OpenPGP cards on the desktop for logging into all my servers but on Android there is no SSH app that supports it.

With the recent release of OpenSSH 8.2, native U2F/FIDO2 token support now exists on the server's end. The client, of course, must also support this. As Termius is my most-often used client, it would be incredibly valuable from a usability and security standpoint if Termius could be updated to utilize U2F tokens for MFA. The capability already exists on all common host OSes: Windows, macOS, Linux, iOS, and Android. It would only need to be added to the app itself.

Add the ability to open connections to all servers in a group (tabs for each connection is fine) so that you don't have manually open a connection to each host when you need to perform work on multiple servers in a group.

It would be create if I can use a cloud service of my choice to store sync-data. I prefer ownCloud or maybe just a scp available storage.

Is it possible to use Termius for serial connections?

I have all of my hosts organised in to Groups, so when I view the main page of the app it looks incredibly cluttered to have my groups and then all the hosts listed below as well. There should be the option to only show groups and any hosts without a group are either a) hidden or b) put in to an "Ungrouped" group. It would make the main UI look a lot cleaner when using groups.

The SFTP functionally limited at present and basic integration with the OS would be welcome—particularly on desktop operating systems. In my usage on Windows, this expected functionality is conspicuously absent and I look forward to its introduction.

In case I need to be blatantly obvious here, I would expect to be able to drag or paste any file—from Windows Explorer, MacOS Finder, and the various equivalents on Linux—directly into the currently open SFTP host session and subsequently initiate a transfer of the file or files being dragged or pasted and resulting in a successful binary transfer to the destination host.

It would be great that a changelog is posted somewhere after new releases.
