+Notes to self
+=============
+chicken scratch we shan't forget, consider this staging
+for actual feature issues on wtv git wrapper-provider we're
+using (no we shan't stick with GH long term likely).
+
+
+cool chart features
+-------------------
+- allow right-click to spawn shell with current in view
+  data passed to the new process via ``msgpack-numpy``.
+- expand OHLC datum to lower time frame.
+- auto-highlight current time range on tick feed
+
+
+features from IB charting
+-------------------------
+- vlm diffing from ticks and compare when bar arrives from historical
+  - should help isolate dark vlm / trades
+
+
+chart ux ideas
+--------------
+- hotkey to zoom to order intersection (horizontal line) with previous
+  price levels (+ some margin obvs).
+- L1 "lines" (queue size repr) should normalize to some fixed x width
+  such that when levels with more vlm appear other smaller levels are
+  scaled down giving an immediate indication of the liquidity diff.
