[Discuss-gnuradio] More "wishes" for GRC

[Marcus D. Leech]

It would be convenient (well, beyond convenient, actually), if there 
were a way to do init-time (not necessarily post-flowgraph-start) flow-graph
  reconfiguration at run-time.  There's currently a "disable" control 
within GRC, but that's a compile-time thing.

It would be nice to have a single flow-graph that has a few minor 
variants, which can be requested at init-time.

For example, my simple_ra tool would be better if one could ask for 
differential (two hardware sources) mode, or interferometer mode.
  Right now, I have to use separate flow-graphs to do that, and 
managing architectural changes among multiple flow-graphs that all share
  a "core architecture" is a bit of a pain.

Also, unrelated to that, and I think I've raised this before.  A gating 
control on a file-sink would be great.  Either a dynamically-changeable 
parameter,
  or a separate "gating" input stream.  Dynamically changeable 
parameter seems like the least-disruptive thing to do if keeping the 
existing filesink.
  It would default to "True", so if you don't use that parameter, it 
behaves as it now does.
