Major improvements to the spreadsheet and SV inspector views​

  • Allows opening tracks in the spreadsheet and SV inspector

  • Uses @mui/x-data-grid for display of the spreadsheet

  • Makes separate columns for VCF INFO fields

  • Support larger files by storing data in 'volatile' storage that doesn't bog down the session

  • Support DEL, INV, and all types of SVs instead of just TRA and BND type variants in the SV inspector

  • Re-navigates existing breakpoint split view instead of launching a new one each time

Saves user sessions in a local IndexedDB​

  • Sessions are saved in IndexedDB instead of localStorage which has much higher capacity and organization, so you won't lose your sessions if your web browser closes!
  • Users can create "favorite" sessions to revisit for later
  • Admins can also create pre-configured sessions for their instance for users

Improved "aborting" behavior​

This is an ongoing refactor, but there is now new improved 'aborting' behavior reducing some of the re-calculations that bog down the UI.

Optimized and improved jbrowse-plugin-gwas​

  • New optimizations added for loading large GWAS style BED datasets to enable better jbrowse-plugin-gwas features
  • The jbrowse-plugin-gwas also added a better clickmap allowing you to see the mouse-over feature https://github.com/cmdcolin/jbrowse-plugin-gwas
