@rkotze can you review this PR before October 31 or at least add hacktoberfest-accepted label to it? I want to participate in the Hacktoberfest event with it (https://hacktoberfest.digitalocean.com/resources). Thanks!

Hi @viperet
Thanks for the pr. I've added the label for you.

Just a few things:

• My Azure CI pipeline was broken, which I've just fixed. Could you update your branch with my changes in 'master' so the CI can run, please?
• Just got a couple of unit tests failing to fix.

I think my issue was not clear on how I imagined this working.

I see you have allowed sorting per section 'selected', 'unselected', and 'more authors' but what I would prefer is you would toggle and it would apply to all sections rather than per section. How does that sound too you?

Sorry for the confusion.

[rkotze]

Please see the previous comment and a couple of unit tests failing to fix.

[viperet]

@rkotze sure, will fix that. Do you prefer parameter in the settings or icon in the sidebar to set sorting order?

[rkotze]

@viperet could you make it a setting, please?

[viperet]

Yes, sure. I’m on vacation now, will return in a week and change this PR according to your request

[viperet]

@rkotze I moved sorting direction to extension configuration and fixed tests.

[rkotze]

This looks great 👍 @viperet
One small thing, could you update the readme with information about the setting, please?

[viperet]

@rkotze done

[rkotze]

Thanks @viperet
