+# TODOs for HNG (Historization NextGen)
+
+## gauges-reference-water-levels
+
+Could be seen as direct part of the gauge data and therefore kept with
+the foll primary key reference...
+
+## Water level diagrams:
+
+One time range might reference different verions of one gauge:
+- How is that hanedled currently?
+- How to handle it in HNG?
+
+## Map display:
+
+Ensure only current gauges are shown in all situations
+- Gauges layer
+- Search
+- more?
+
+## Bottlenecks:
+
+Always associate the correct gauge, when:
+- Uploading Sounding results (how is that currently handled?)
+- Displaying Sounding data
+- Creating/showing X-Cuts
+- Unclear: what constraints shall we chekc for on bottleneck imports?
+
+## EVERYTHING ELSE
+
+Not being mentioned here, doesn't mean something is done...
+
+
+# DONE
+
+Stuff done will bemoved moved here for reference:
