I would the option to pay 5€/month to “boost” the perfomance of a Board which is very heavy. Meaning a board with tons of Fotos or PDFs.
After the month it can be downgraded again and be kinda laggy. Just to have the option to boost it when in actual use.
I don’t know how much perfomance depends on your guys servers and how much on my PC, but if you can have this boost option on the server side, that would be amazing.
