Add totals under columns on folios.
Either totals (eg total gain/loss today) where more appropriate, averages (eg % change).
The total I want is the anticipated income from dividends because it is that feature that dominates my investment policy.
Note that moving averages (like %130d MA) should not be summed but averaged again -- alternatively have the option to select a mathematical op to be applied on the values (min, max, avg, sum..)... of course selecting garbage will result in garbage, but still would give a nice flexible option.
Implement this both for folios and (custom) screens, please!
