Hi, I’m the author of ProtoFluid.
Thanks for the mention, it’s greatly appreciated. I’m hard at work on some significant upgrades. Consider version 1 a ‘proof of concept’ ;-p
I can’t believe I’m actually on this site commenting on my own app!
Thanks again,
Edward, @opticswerve.
Thanks you for your efforts. We hope that this post helps you in gathering some feedback for further improvement. Keep up the good work.
Indeed, if anyone has any features they would like to see, please feel free to do so!
Thanks,
Edward. @opticswerve
The preview version of ProtoFluid 2 is now available at http://app.protofluid.com
This has a lot of the features turned off, just testing that the basics work for everyone, but I’m sure you can see where it is going.
Thanks!
This is very interesting. I can see why this would be useful to many people as well as myself. Thanks for posting this. Sometime this week I will definitely try this out!
