I did send email about this already. But I think it will be better to report issues and request here
Issue in Beta 2. After starting Core Tunnel I get prompted with Window to enter Key. I already did this before.
Request for Beta 3. Please add autostart to settings. This was the case in SSH Tunnel
I just had the time to have a look at the app, and one thing I noticed was that the contrast color (green on this picture) doesn't allow to see with ease the parameters hints colors. At least for me it's not that clear.
Also, something I've seen in another app is really great and clear from my point of view, cause I often forget in which direction those things are connecting. In the following image, it's clear which provides the service (it's even named following the port number you enter) and where it connects to.
Voilà, I hope these pictures can inspire you, and that maybe you'll provide some simiilar feature, I think that would be nice to have for the kind of price tag you ask.
SSH Tunnel has similar diagram for a long time, but at the cost of quick edit – every time you modify a port forwarding, you have to edit it in another window. That’s inconvenient for skilled users.
I’m obviously not defending the current solution, we need more time to find out a balanced way.
