Is your feature request related to a problem? Please describe.
Batch signing is already fine, but having to install all apps one by one is time consuming.

Describe the solution you'd like
The solution I wanted is available from this fork here
I'm using the compiled app, which is available to download here or on the release page.

Describe alternatives you've considered
Considered using Esign, but UI is far better on Ksign and Esign is not updated anymore.

Additional context

I vibecoded this so probably not the cleanest code, and I didn't test this version that much.
So far i'm using it and it's working fine.

Would love to see this officially implemented.

Feature added :

• Removed Signing button from Signed Apps tab
• Added Install button to Signed Apps tab
• Bulk install (install all signed apps selected by using the new button)
• Added a new popup menu when clicking the Signing button to chose between Sign Only or Sign & Install
• Bulk sign & install (sequentially sign and install selected apps one by one)
