Hi

I think this add-on is great and it helps me to use Anki in a certain way. I am currently thinking about switching to Anki in my studies.
Do you plan to keep on updating this add-on for future versions of the software?
Will this stay compatible with the qt5 Version ? I am on Mac silicon but need to use the qt5 version since version 6 runs very laggy here.

Best Regards

Hi,

Thank you for your praise. Iā€™m surprised that you find the Qt6 version buggy - are you running one of the newer versions of anki that have Qt6 support on Apple Silicon (rather than an Intel version)? see: https://apps.ankiweb.net/ for download links.

I myself am running Anki Qt6 Apple Silicon and face no lag.

However, if you still are facing issues then please reply to this again and I will see if I can dig up the old code. Even if not, it should only be a few lines of code different between the Qt5/Qt6 versions.

Hi,
I used the qt 6 and for some reason anki was laggy on the whole. However, rendered browser works on qt 5 perfectly. In my case, way better than on qt 6.
I was wondering if this is due to me having used Rosetta in the past for the old Anki versions?
Do you think that this add-on will stay compatible with qt 5? And if I understand you correctly, you intend to care for that add-on in the future?

Hi,
A very basic question, sorry. How do I access the add-on?
I added it to my Desktop Anki but canā€™t figure out how to use it. I am expecting the option for an additional Browser window but donā€™t see it anywhere.
Thanks and regards,
Johan

Hi Johan. If you take a look at the 3rd screenshot on the add-on page, there should be a ā€˜renderā€™ button next to the cog icon to the right of each deck name.

I havenā€™t tested the add-on in a long time so there is a chance it could be missing.

Hi Sam,
Thank you for the quick response. I was blind sorry.
It does not work though, but Iā€™m using the updated version by ā€œShigeā€, which does work as you intended.
Thanks for a very useful addon.
Regards, Johan

Hi Jasmin,

Nice to see people are still using my add-on from 5 years ago. Iā€™ve pushed an update which should fix it. Either close and reopen Anki, or navigate to Toolsā†’Add-onsā†’Check for Updates.

Iā€™d appreciate if you could verify that it works for you now.

I might look into rewriting this add-on soon to improve it :slight_smile:

Best,
Sam

Thank you!! Now it is working!

Itā€™s just a little ā€œbuggyā€: windows are opening and closing really fast for every rendered card, but I can live with that :slight_smile:
