Categorisation colors

When switching between months, the color of each category changes, which makes it hard to track down the changes in proportions from one month to another. Each category (e.g. transport) should have an assigned, constant (possibly customisable) color.

Hello. Thank you for your feedback ! This feature is on our roadmap, but not at top priority, so we will not do this in a very near future, but it will come ;)
