What are the analogues of the WinSCP + Putty bundle for OS X?

Question

SSH

For a long time I used a bunch of WinSCP + Putty on working Win-machines and even on a personal macbook (via Wine) in order to maintain the same environment everywhere. I really liked the integration between them: I always started sessions with WinSCP, Putty automatically started, key authentication was basically, and where there was no such possibility, WinSCP could forward the password to Putty. Now nothing keeps me on Win (the work computer is also a poppy) and I want to find the closest replacement.
The requirements are simple:
Mandatory:
1) Dual-panel interface
2) Button/hot key "open terminal", it doesn't matter if it's built-in or external
3) support for agent forwarding (our company uses a system of dynamic key issuance that expires once a day, you need to connect to a special ssh host, enter a password and OTP, after which you receive a key in the memory of your ssh agent for 24 hours)
4 ) tabs (tabs)
Desirable:
1) built-in text editor
2) the ability to specify additional editors by file type
What was tried:
1) FileZilla - brrr ... Well, it does not satisfy paragraphs 1 and 3
2) ForkLift - Cool, but does not know how to point 2
3) CrossFTP - does not know how to point 3
4) Transmit - does not know how to point 3
5) Commander - almost perfect, but does not know how to point 3
6) iTerm2 - smart replacement for Terminal.app, but no two-pane SFTP manager
7) CyberDuck - can do steps 2, 3 and 4, but not 1 :(
8) YammyFTP - can't do steps 2 and 3
What other options are there? Maybe add-ons over Terminal.app?

Answer 1

If you really want a "two-pane interface" - try Double Commander.
