I previously used a similar service, and I found that once I had utilized all the available templates, the service became quite restrictive. For example, if I used a logo intro animation for one client, I couldn't easily use the same one for another without it being apparent that a template was involved. This quickly limited its usefulness for my work.
I'm wondering if your platform provides various ways to showcase templates, or if there are options to customize them significantly so they don't look identical when used multiple times. This is really important for the kind of projects I'm planning to create on your platform.
