Thank for the quick reply,
That is a bit unfortunate indeed. I do not have the funds to sponsor this now. But I will try to raise something if possible. May I know (in private message may be) what would be an approximate estimate for this task?

I’ll drop you a line 👍

Thank you for the awesome plugin! But there are some issues I can’t deal with. I’m not sure if these are bugs or caused by wrong settings.
1. When I tried to go back to the topic list, the scrollbar will return to somewhere else instead of the last visit part.
2.I tried to enable topic list action and they look fine. However, it randomly highlights the bookmark button, even though the topic has not actually been added to bookmarks.

That’s currently not supported. PR welcome

That’s very odd, I cannot presently reproduce - are you on latest version of Discourse?

@Niels_Dewitte sorry this took so long, but a PR was always welcome to fix this.
Thanks again for the report. This should be resolved now.

Hi, how do I use the thumbnail picker in [GitHub - merefield/discourse-topic-previews-sidecar: A Discourse plugin that complements the Topic Previews Theme Component to add features · GitHub](https://github.com/paviliondev/discourse-topic-previews-sidecar)?

It’s a button in the topic meta editor:

I have, and I rebuilded few hours ago.
I know. That doesn’t help you a bit, but it means your issue isn’t by some general bug.

@merefield
I noticed that your [recent changes](https://github.com/paviliondev/discourse-tc-topic-list-previews/commit/dbe22caff654a01735f3e3cf2e6b6cff5e0b1296) from two weeks ago removed the usage of the `Ember` global. However, it will fail if you use Ember 5!
For example:
Suggestions:
- `computed.bool` → `bool` → `@ember/object/computed`
- `run.scheduleOnce` → `scheduleOnce` → `@ember/runloop`

Nice catch @Arkshine! This deprecation is [`deprecated-run-loop-and-computed-dot-access`](https://deprecations.emberjs.com/v3.x/#toc_deprecated-run-loop-and-computed-dot-access). Messages about that would’ve shown up in development and test environments, but it looks like they were being optimised out of the production build.
This will make the warning work in production builds of Discourse under Ember 3.28:
[https://github.com/discourse/discourse/pull/25074](https://github.com/discourse/discourse/pull/25074)
(by default Ember optimises all deprecations out the production build, so we have a to do a lot of work to undo those optimisations)

Thanks David. Yeah that would be why I will have missed them. As a Theme Component I generally check for deprecations against a current Production build as I use the Theme CLI (and none of my Production builds are running Ember 5 just yet so …).
Great catch @Arkshine !

What does the `after_code` section of your `app.yml` look like?

What would I be looking for ? I don’t have any error showing for the plugin. [Topic Previews Sidecar](https://github.com/paviliondev/discourse-topic-previews)
The installed version is:

Do you have Theme Component active in the current Theme? (you must have the Theme Component as well as the plugin running)

I’m using the blog style on two categories and tags, so yes it’s active. Let me try a different theme as i’m using the [Kodular Community Theme](https://meta.discourse.org/t/kodular-community-theme/162724)
