An application that would make donating to FOSS projects, especially GPL-licensed works (or at least: those not trying to cater to corporations) in desperate need of support, effortless. In that: a periodic budget can be determined, time spent actively using applications is tracked, an application's userbase is taken into consideration (as their cumulative income may eat too much into budgets: possibly better spent supporting smaller projects), and personal preference can be given (including an option to filter license types); as to rank the applications based on perceived value, and fraction the budget accordingly.
I would be happy to support projects that I actively, or to a lesser degree, rely on. But the process of taking all steps required to support a project is simply too manual, and outright unmanageable, when trying to take into account all system components. I really want the incentives to shift from MIT to GPL, so that maintainers don't effectively end up being controlled by corporate paychecks; and are rather supported by individual end users. This should in theory make FOSS more resilient to any future restrictions to source access, which could hamper the long-term parity of forks, seeking to strip anti-features.
