Hi John,
Thank you for sharing your feedback about the Toolset Blocks and I'll pass it on internally.
The Toolset Blocks is continuously improving based on the feedback and suggestions that we receive and it has in fact grown a lot from its initial release.
The other page builders do have years of head-start, but we're also fully committed to developing Toolset Blocks into a fully functional page builder that offers all the necessary features that users of other page builders would expect and more.
Based on what you've shared, I understand that your goal is to design the repeating loop item part of the Toolset post view, using the Oxygen builder.
This limitation arises from a fact that while other page builders like Elementor, Divi, etc apply their templates at the page's content level, the Oxygen filters or take control of the entire page's output, bypassing the theme.
( hence it can be referred to as a "Theme builder" rather than a "Page builder" )
This is also the reason that you don't see an option to design the Toolset view's loop item using the Oxygen builder, when on the view's edit screen, unlike the other page builders ( like Blocks, Elementor, Divi, etc ).
With this in mind, I understand you have a couple of options to complete this and other similar post lists/sections:
1. You can achieve the desired layout of the Toolset view's post list without the Oxygen builder, using Toolset Blocks and custom HTML and CSS adjustments ( where needed ).
OR
2. If you find the option 1 limiting, you can try switching Oxygen builder with a different page builder like Elementor or Divi.

OR
3. If you'd prefer staying with the Oxygen builder, you can check out it's "Easy Posts" feature, to generate a customized post list, instead of a Toolset view:

I hope this helps and please let me know if you need any further assistance around this.
