Hi all, I have some remarks regarding the current state of the filter design tool.

Recently Edward Kigwana worked on porting the filter design tool from PyQwt to PyQtGraph. Unfortunately he wasn't able to finish up porting everything over, so now the filter design tool is half done. The results (in one squashed commit, rebased on GNU Radio master) can be found here [0]. Despite the lacking features the plotting and filter tap generation are still working. I will submit the current progress as pull request and maybe we can even merge it so you have a good starting point. I have no objections if you want to redo the PyQwt to PyQtGraph porting yourself. But since there has been some work in progress I want to make sure y'all to know about it. Cheers Andrej [0] https://github.com/noc0lour/gnuradio/tree/pyqtgraph_squash
