The lightkeeper from kalaksi

Color/theme distortion after adding new machine

Support for SSH Passphrase

Pretty much the title, I mainly use ssh key with passphrase and lightkeeper doesn't support that.

Active connections are terminated when add/delete machine. There is no problem with one or two machines, but as the number of managed machines increases, opening closed connections will negatively affect the comfort of use.

Improve flatpak/desktop icon

Hi,
square icons are not really nice to see nowadays. I attach a rounded version.
You can easily get it by using ImageMagick:

$ convert io.github.kalaksi.Lightkeeper-128px.png \
     \( +clone  -alpha extract \
        -draw 'fill black polygon 0,0 0,30 30,0 fill white circle 30,30 30,0' \
        \( +clone -flip \) -compose Multiply -composite \
        \( +clone -flop \) -compose Multiply -composite \
     \) -alpha off -compose CopyOpacity -composite io.github.kalaksi.Lightkeeper-rounded.png

Also remember that only 128x128 icons are required for Flathub apps right now.

Why not use qrc, and tried to use filesystem files?

lightkeeper/src/frontend/qt/qml_frontend.rs

Line 103 in 8692eea

engine.load_file(QString::from(main_qml_path));

I'm trying to create a Nix derivation of this but found that always is used in the file://, so manually the qml must be copied to result derivation. If these resources are already in a rc, why not use that rc?

Has the code been independently reviewed?

I would love to try out an application like this, but the idea of running it on my machine freaks me out since it would immediately have ssh access to a lot of servers which is insecure for obvious reasons

My point being is that there should be some independent reviews attached to every release/version. Of course everyone could just study the code for themselves but that's just basically too much work.

Also the readme has no explanation whatsoever what access level is required, and how the data is fetched.

Not run v0.7.0

Even though I deleted the ~/.var/app/io.github.kalaksi.Lightkeeper/ directory, it does not work after the update.
