I like the idea of being able to sort/filter the subscriptions in some way so that you can see which are the annual subscriptions. Perhaps the subscriptions page could get filter options such as weekly, monthly, annual, etc (in addition to the current all subscriptions view).
Also like the idea of being able to select specific future months to see predicted committed spending in that month. Maybe a graph would be useful for this with predicted committed spending plotted as bars for future months and then you click on that bar to see further details. Maybe that would be best in the analytics tabs but with future months available - not just current and past months.
One additional suggestion I would like to make is to do with how subscription values are displayed in the subscription page. At the moment it just shows (predicted) transaction value. I think it would be useful to have a view toggle to also display annual equivalent value (so for monthly subscriptions this would be value x 12). I say this because I manually maintain a spreadsheet list of all my subscriptions and direct debits and for my monthly subscriptions find it useful to have both a monthly spend column and an annual spend column. Seeing the annual spend of each subscription listed in this way makes it much easier for me to decide which subscriptions I’m happy with (from value perspective) and which need to go (compared to considering just monthly cost).
All in all, it seems there’s a lot that could be done to subscriptions and committed spending tracking to make more useful.
