A new competitor import plug-in is available now for YachtScoring (see https://www.yachtscoring.com/).
You can simply enter your YachtScoring event ID (e.g., 13062 for the Bacardi Invitational Winter Series)
and start importing your entries from YachtScoring into the SAP Sailing Analytics.
+ The administration console has undergone
+ some technical improvement. Panels including their code and data
+ are loaded only when needed, significantly reducing initial code
+ and data download. Furthermore, all panels can now be navigated
+ to by a fragment identifier. Example: https://dev.sapsailing.com/gwt/AdminConsole.html#RegattasPlace:.
+ These places become part of the browsing history, so the back/forward navigation in the browser is now
+ aware of the click path and how it went through the panels which turns out to be particularly useful
+ when leaving the AdminConsole through a link opening another URL in the same tab. Note, that furthermore
+ it is now possible to construct AdminConsole links that have a filter and/or selection in place for the
+ main table in the panel (should there be such a "main table"). Example:
+ https://dev.sapsailing.com/gwt/AdminConsole.html#RegattasPlace:filter=Trave
+ which shows only regattas containing the string "Trave", or
+ https://dev.sapsailing.com/gwt/AdminConsole.html#LeaderboardGroupsPlace:select=0b7e71c5-f944-4650-bf09-f902ce76c3d3&filter=0b7e71c5-f944-4650-bf09-f902ce76c3d3
+ which selects and filters for a single leaderboard group.
