Yes, we are planning a new dashboard and this is the main reason.

The ExtJS chart engine does not offer a dedicated title option, but I just found a way to work around it so this will be available in trunk shortly. Currently, the chart title is simply displayed on the toolbar, next to the "update" button.

The visualizer is designed to be as network friendly as possible. That's why the chart type buttons don't execute anything (just think of them as a way to select the chart type). The chart is not updated unless the user specifically clicks the "update" button. Otherwise, if the user e.g. wants a different chart type and different indicators, and selects the chart type first, the chart is unnecessarily updated (and data transferred) twice.

Improved notifications is already on the 2.6 roadmap. In trunk the "Form is not complete" is replaced by something a bit more informative, like "No indicators selected", "No data elements selected" etc, but this will definitely be improved further.

Please feel free to provide feedback any time.
 
Thank you so much to all the developers for making our lives easier with DHIS2.
