We have received the request (we found it regretfully in our spam folder) but the issue here with this plugin is that the development is a bit steep in costs. We need 25 hours to develop this plugin and our hour rates are Euro 85.
We have offered this in the past to multiple users but we need to organize a pool of users who want to financially cover this development so we can program this.
Note that it has also a consequence that some of the BF core-files need to be hacked and with every update of BF this need to be redone (but we will document these hacks wel). Due to the structure of BF no option is available not to hack the core of BF in some places. No option....
So I will chat with Markus and arrange a post here on the forums where users can join the group of users that are willing to pay for this development
I understand it will cost money to develop and we can pay some cost but it's very limited.
I think I have to use a concurent form builder with mollie intregraded. That will cost us €20 euro and it's done for now.
I hope you can find more people to paid for development costs so whe can use BF again.
