Adding a few items here that I feel can vastly improve the platform. It is possible some of these already exist or planned to be included.
Run Analysis on Dashboard load: This will provide an excellent way to handle metadata display
Allow Normal Dashboard tab to have Blueprint type behavior.
Script include - many analysis might be using the same type of code over and over again. Is there a way to create canned functions and then call them from different analysis?
Formula for dynamic table: Please allow the same column to be added to the dynamic table multiple times with different formula. Currently it is not allowed, and produces an error on save. Although, you can add the same column but the formula gets overwritten.
Custom widget: It is great it can load custom html, but again this widget can only accept a device as input. If it could accept a JSON object from an Analysis and that could be used as a parameter for the HTML, it would be an excellent feature.
Object data store: A device independent multidimensional and hierarchical object data store will be very helpful.
