Main Dialog & Book Listings

• Dedicated Goodreads User Shelf browser: New standalone tool accessible from the toolbar menu to browse any Goodreads user's public shelves and reviews via list RSS feeds.

Glad you liked! Wow. Never been to Buenos Aires but I hear book stores and libraries are awesome.

Amazing work.
Goodreads> Most read - my country and the Most read - The world - this week shows the same list for me in the plugin which is The world - this week (opening the source shows the right list), so I went to add a custom source to be more specific, but seems I can not. nothing added.

Thank you, and I appreciate the early feedback.

I'm aware I chose to release this before doing more extensive tests, but I wanted to hear opinions.

Good catch. Shows the same list for me too in the plugin, while the Browse Source points to the correct URL. Will fix it ASAP.

There is a remote cache in place, which loads the list from Github. I need to override that to not use the remote cache for the My country list, since that is a dynamic Goodreads page that delivers geolocalized content.

And hopefully add support for this types of URL:

https://www.goodreads.com/book/most_...=AR&duration=m

So user can add their own country listing manually, if needed.

I've found a regression that broke some sources loading. Soon to be fixed.

[Karellen]

Hi @Comfy.n

Just noticed your new addon. Looks fantastic. Just installed it and will take it for a spin.

Fixed!

Please update to latest version 1.1.1

[Karellen]

Yep, that fixed it.

Just starting to play with it now, how do you filter the results. Let's say I want to find SciFi only. Can I do that?

[Comfy.n]

Thanks for confirming fixed.

Well, unfortunately one must load only one list at a time. So I suggest you type 'Sci' in the filter box above the sources left panel and select one of the matching lists.
