@K8Sewell, Thanks for the PR! I’ve done a round of testing and wanted to share my findings. Hopefully these details are useful and of course, I’d be glad if others could also take a look and confirm.

Layout comparison
I noticed a difference in pixel layout between audio and video when comparing dev and your PR (#1495).

Dev (audio/video viewer):

• contentLayout: 808px × 630px
• mainPanel height: 691px
• centerPanel height: 675px

0penSeadragon manifest Layout
Main panel leftOption: 559px

PR #1495 (audio/video viewer):

• contentLayout: 808px × 720px
• mainPanel height: 781px
• centerPanel height: 765px

0penSeadragon manifest Layout
Main panel leftOption: 781px

Other issues:
Index tab not loading data: Even after selecting Sort by date or Sort by volume, no info is displayed.

Thanks again for working on this PR! I really appreciate the effort, and I’ll be happy to retest once updates are made.
@demiankatz, I’ll leave it to you to decide whether these should be addressed before merging for consistency, or if they can be handled in a follow-up. Thanks also for your time!

Thanks for the testing, @LanieOkorodudu -- something strange is definitely going on here. I can think of no reason why integrating the AV component should change anything outside of the AV component, but somehow certain manifests no longer load correctly, and default behaviors of other modules are different. I think further investigation will be needed!

Unfortunately, as I mentioned on the last call, I am currently overwhelmed with work in other projects, so I am probably not going to be able to look more closely at this for some time. I wish I had more bandwidth, but I simply don't at the moment. I will try to revisit this when possible, though!
