I have purchased the Gold edition/subscription of MRA for 2 reasons:
to have full access/control/options in MRA (webbased) to create/edit routes
support the MRA team
I do like your idea about a donation button. Users can donate a certain (small) amount to support the MRA team.
However, if someone donates (let's say) €10,00 per month, after 12 months this amount is €120,00! So you are able to purchases the silver/gold subscription as well.
If you prefer a "1-time-and-never-again" donation, the MRA team might receive a lot of small donations something like between €1 and €10. I'm not sure if this could benefit the MRA team on long term period. Ofcourse, any donation is absolutly welcome.
At some website i see a donation button with fixed amounts like €2/€5/€10 etc.
That might be a solution to avoid everybody giving just €1 once a year.
But in overall, great idea!
