We will be adding an updated shared leaflet studio for AcuGIS clients.
The current studios at https://studio.acugis.com and https://omeka.acugis.com will continue to run for those that are using them.
The current commercial version, which you can view (and use) at https://studio.mapfig.com, includes a number of feature enhancements, updated marker set, and new UI.
This same version will be made available to all AcuGIS clients at https://leaflet.acugis.com later in the week.
