Since kernel interrupts may not work during queries due to autobahn limitations, it may be good to introduce an argument to queries to limit the maximum number of neurons returned. A default of 300 or 600 is what used to be available in Hemibrain NeuroNLP. Another possibility is to have a UI button that stops incoming Neu3D data from being parsed until a message is retrieved, which will make the UI not load any more incoming data for the current query.

I think part of the anxiety is that the data are not shown as the data comes in progressively. You feel that something is happening in the NeuroNLP website with this query.

Edit:

Take that back. Waited 2 more minutes and found out there was an error on the backend due to my database issue.

The error message from NeuroArch server is not shown in the fronend, which is probably part of the problem of message discussed earlier. See issue #25
