Performance Manager Chart:
1) Add date sliders for more functional zoom in/out via PC
2) Ability to select/deselect y-axis components in their entirety

Activity - "Analyze" Screen:
1) Fix visual bug of Performance metrics box (cadence, HR, etc.) remaining "on" / not clearing after selection is made

Dashboard Screen:
When adding a chart, existing charts and layout have a tendency to go haywire, especially if you want to scroll to a different location to drop the chart. Lock the current layout until the desired location is selected. (PC)

Dashboards:
1) Consider "Trellis" option so you can compare various values by different sports on one chart (e.g. Time in Heart Rate would have two sets of vertical columns, one colored for bike and one for run.)
2) Similarly, add the ability to compare two different time periods on the same chart.
