Hello,
Hopefully this is the correct place for this sort of question, but I am mostly trying to decipher what the functionality limitations are between Gosling.js and HiGlass. I am hoping to build a set of Gosling visualizations within an existing React application. The things I am hoping to visualize are:
After exploring whats functionally possible with Gosling, I ran into multiple notes in the docs about how something is "only possible with a HiGlass server". For example:

There is also discussion here that references fasta support for Gosling: #184
However, if I jump over to HiGlass, I find the following example: https://higlass.io/app/?config=TA_BP0R5R8GfKHkKX7-TzQ
Which is a sequence + BAM viewer, which is 80% of what I need. When I inspect the viewConf it appears that the only thing coming from the actual HiGlass server is chromosome labels. The fasta and bam files are just URLs. I think I am just confused about the different modalities. I can envision a few different cases:
In other words, it would be impossible at this time to build the visualization I want in Gosling.js, even if I have a HiGlass server. A fasta track is just not supported in Gosling.js.
