I get that you make that a Pro feature, but this sucks. I just gave you $150 and your branding is competing with my branding. This is just bad business. The other features of pro should stand on their own without the need to create what feels like extortion.
You should remove your branding with ANY purchase, which is no different than freemium removing ads with any purchase. I simply don't need all the pro features because I am a small business.
You guys do this and I'll sing your praises. Right now, I'm annoyed.
