Yes, I saw Erel's page. That's where I downloaded the .zip file from.
Erel's instructions:
Add TabStrip with the designer.
I did not see this component in the designer (pretty sure its because I had not added that library to the library manager list). Erel might be assumings most folks know how to set up an external lib like this but I don't.
>Tabstrip is an additional Library.
That statement means what? I have to download the Library file from another location? Github? I did the download from Github and unzipped that file but I have no idea what file I need to grab from all of those files. Those Github files don't like anything that I can run in B4i.
