Libra 2 Conversion flow for Manga on Libra 2

[mgrimace]

What's the best way to read Manga on the Libra 2 in 2024?

1. Manually copy CBZs directly to device
2. Kindle comic converter (KCC) which appears to output to kebup, then manually copy to device
3. KCC then Calibre, then send to device via KoboTouchExtended (KTE)
4. Something else?

I tried KCC first for .cbz -> .kepub, then copied into Calibre, and KTE still converted the files despite it seeming like they already should be in kepub format so I'm not sure what's going on there (e.g., if this step is redundant now).

And along with conversion, how are folks doing metadata, especially for larger collections?

My goal is to simplify my workflow, and to use the full screen (e.g., stretch/upscale).

Thanks all for any advice!
