Modern List Manager replacement?

[cluster_fsck]

I'm doing some personal retroprogramming and looking a List Manager replacement and wanted to see if folks had any ideas. The List Manager that ships in classic Mac OS is horribly limited and has little utility value for what I'm trying to do. I previously did a ton of classic Mac OS coding, but for these projects I'm going to use Carbon because the Carbon Event Manager makes me happy so am looking for a List Manager replacement that would be Appearance-savvy (my target OSes are 8.6+) and fit into a Carbon world.

I'm experimenting with building a Mastodon client for classic Mac OS and looking to avoid writing my own timeline component from scratch to build off something that might be out there. I did some experiments with the Data Browser component but it's really not suited for my use case. Any pointers would be appreciated!

Yay, that’s exciting! I’ve always wanted to look for something like that to build a columns filer browser that’s more flexible than Greg’s Browsee.
Did you trade off MacApp vs Carbon when you were making the decision?

My issue with MacApp is that I loathe C++ and really don't want to code in ObjectPascal, either. I'm using Carbon because it's going to be easier to deal with running tasks than the classic WNE loop and I can get back to a reasonably modern OS. As much as I love System 7 and before, it's just not practical to think about creating a network-centric app with an infinite scrolling mechanism for me -- I need some more modern footings to not a) pull my hair out completely and b) have a shot at actually getting something running.
