No idea how 4.x handles it, but it does have settings for logs and I found some logs on the device.
I believe the logging is automatic (or was last I used Devmode).

this is not necessary anymore (unlike you need readings statistics). It opens all kepubs and epubs with TENG.

This was a suggestion for when you are forcing ePubs to use RMSDK and want to open an file with TENG. My quick test seemed to show that using kepub.epub will force the use of TENG.

Since JSWolf is not running a v5 firmware and likely does not have a device capable of running it, just an intellectual exercise for him in asking that question.

Sure. Just set the font to anything but the publisher font. If the weight can be set, it's RMSDK. If it only switches from regular to bold it's TENG

If I ever get another Kobo, I want to know what I'm getting into with the newer firmware.

I'd very much call the 5.x firmware a work in progress.

There's bugs, it's somewhat slow. But you do have access to Adobe's renderer if you need it, which is a good fallback. I generally consider it a downgrade from 4.x (for now) unless you frequently use the built-in browser. Chromium driving the browser means all web browsing on the device receives a major upgrade.

For pure reading, I think you can objectively say that the reader app is somewhat slower than the previous one.

From a security POV of course it's good that they've updated their system software stack, but I hope they continue to polish the reader app specifically before they call this release "done".

(They did finally add a clock!)

Do you know if RMSDK in 5.x has been upgraded? Does it support font-variant-caps: small-caps;?

Firmware 5.18 also supports lcpl files, which 4.x doesn't. And, you can directly download acsm files from the browser without the need for a PC.

No, it's still pretty old. No small caps support.

A few questions came to mind just now:
Would it integrate so deep, that it syncs the reading progress with Nickel so that the server has the latest reading position?
Would it also integrate with the reading stats?

I have ADHS, so numbers going up make brain produce dopamine

That's the plan, yes. Stay tuned for more news in the next month.

(There's also going to be a checkbox in Settings > Reading in Kobo's settings menu that will let you pick how you want to open books, so you won't need to uninstall the mod if you want to use the built-in reader app.)

Really well thought out. Let me know if you're looking for beta testers.

Definitely. Can I DM you?

I also just noticed that they dropped software 6.0 officially, so I think I'll be looking at that and perhaps fast-tracking the NickelMenu changes next.

Yes, please DM me if you like.
Tolino doesn't have the 6.x firmware yet and I hope that the reader will just work like Nickelmenu for now.
