1) Enable us to switch off the description of aggregation applied to a measure when showing multiple measures - for example, today we see "Sales Year on Year (Mean; weighted by Sales LY)"... this is useful for an 'analyst' but far too wordy for end user dashboards... we would just want to see "Sales Year on Year"
2) Allow us to Colour by Measure - in a multi-measure Bar view we can colour by many different things (panes, splits, stacks etc.) but not by measures...
Starting from 2.6 b284 onwards you will be able to hide function names in the data titles. The option is located in Toolbars > Toolbar settings > Show function in data titles.
