Tracking the impact of SasView
- Metrics: Users, downloads, publications, citations
- Download statistics: https://tooomm.github.io/github-release-stats/?username=sasview&repository=sasview
- Publications: https://www.sasview.org/publications/. Need to update list on Zenodo and fix the bit rot in https://github.com/SasView/saspubs
  - Also note that fixing the code will not do much unless we also update the Zenodo database with actual publications
- Usage analytics: Revisit https://github.com/SasView/sasview/pull/2702?
ACNS tutorial proposals open...

Venue scouting: Prague / Paris (SOLEIL or LPS Orsay) / ILL - Paul to give update
- https://github.com/SasView/sasview/wiki/CodeCampPlanning
- Soleil not possible for 2026 due to availability of conference services. 2027 or 2028? Start planning now!
- Dominika is very interested to host in Prague - Paul B. in contact.
- ILL - Paul G. working on it.
Next step: once potential hosts identified, send a location poll
- Maybe take all for different years? How to chose which is which? does one offer prefer 2027 or 2026?

Discuss:
- Use the browser instead of built-in window - https://github.com/orgs/SasView/discussions/3511 (related PR: #3847 — Remove QtWebEngine; use system browser)
  - Question was raised as to whether this should just be a usual PR change or an actual ADR. Most seemed to believe an ADR was appropriate but agreed some more discussion should be allowed.
