Drop idea "D365 Tools Window" - not re-inventing XrmToolbox concept
Instead provide your "tools" as XrmToolbox plugin for paying customers, if the tools you sell offer a reasonable extra value compared to those already available in XrmToolbox.
Rather focussing on things XrmToolkit differentiates from any other tool.

Yeah. XrmToolbox is freely available and why should development time be wasted on stuff that is already available?
