Solid PDF Tools v8 User Interface
The v8 rewrite was a conscious shift back to our core features : a focus on document reconstruction functionality.
Adding new features to the product going forward is prioritized by customer requests so please send your feedback to email@example.com.
The v8 rewrite was required to take advantage of 64-bit architectures and multi-core processors. A rewrite using Microsoft .NET was required so that we could engineer the product using our own Solid Framework SDK (unlike the older products which were based on a legacy architecture).
