Hi @rowifi -
I will agree with @ScruffR. If the duplicate text in the .cpp file is the only problem that can be solved by:
, I would be happy to continue using WebIDE. For most of my projects I use WebIDE, but full disclosure, they might not be nearly as complex as some projects in this forum. To me it is 'easier to use' 
I have used WebIDE for this project, which was my most complex one to date. The only hurdle I ran into was I was unable to get a particular custom library to function. I would pin this rather on me not being able to get it to work as apposed to a WebIDE problem.
Having said this, I managed to add this particular library using Workbench and CLI in a couple of seconds. I recon there is scope for both, depending on your need.
Best of luck!!
