Hi, I'm afraid that you must purchase the Pro version before you attempt to make changes to its PHP code. Sure you can do it on the non-Pro version but you will get errors here and there. I've been through that mistake so I know what I'm talking about. Once you get the Pro version, you can do any layout changes to its themes.
Is that true? Also, am I jumping the gun on hiring someone to build that feature out? It will cost me around $200 to get that feature added in. Just wasn't sure if the free or pro version will be coming out with feature soon. If so, I could wait perhaps.
