We have introduced new styler for vector layers. These layers can be drag and dropped from your computer, added from URL or checkout from CSW catalog. This added styles can be then saved to map compositions to create thematic maps. We are working on more advanced functionality like SLD import/export. Conditional styling and labeling
After incubation in our environment we finally moved HSLayers-NG to github. We hope that this will atract more users and developers.
