 ## Disclaimer and afterword
 
-The library is intended for large GUI applications. The definition of `large` is
-quite arbitrary and means something in the range 20k - 200k lines of code. The
-main logic here is that using the additional library for smaller Qt applications
-is redundant, Qt has everything that may be required. If a small GUI becomes messy
-with time, it can always be refactored or even rewritten from scratch.
-
-However, when the number of views to show the same data is getting large, and
-the GUI enters the range 20k–200k, this is where a given library might help in
-proper separation of data, logic, and UI. When the GUI grows even further, well,
-developers of such large GUI know already what they need and probably have
-already implemented similar machinery.

-The project is under active development.
