My point is valid. It's inconvenient and (imo) unreasonable to suggest
a person should have to use a second system just to create a remote
config. Aside of that, they may not even have a second/desktop system
to use. If a tool can't accommodate a perfectly capable system, the
tool is the problem, not the system. Also, it makes no sense to make a
gui app the standard when there are plenty of use-cases where a
desktop is unwanted or unnecessary, and where an existing command line
tool has worked for years.

I see no reason irrecord and IrScrutinizer can't co-exist, especially
when IrScrutinizer is not a drop-in replacement for the reasons above.
I know a lot of people who wouldn't bother with IrScrutinizer because
for them it would be too much of a hassle.

> Having said that, suggestions for improvements are always welcome.

Remember, we're only talking about a simple way to create a remote
config in most cases. That shouldn't require a desktop environment and
sophisticated app. It would be better if IrScrutinizer could be the
sophisticated gui app for people who need it, and a simple
cli-friendly app for those who don't. I have no clue how it's designed
though so I don't know if that's even possible.

A good rule-of-thumb to follow is simple tasks should be simple, and
always have minimal requirements.

I'll have to check which receivers I have - I do have a few different
ones (TSOP34856, TSOP38436, TSMP58000 for sure). I'll have to look
into the 38438 and 34438. I recall an oddity though. The remote I use
is supposedly 56kHz, but it works perfect with my homebrew serial ir
which is 38kHz. It also works with a 56kHz ir receiver I have. So is
the remote 56kHz or 38kHz? Or do I need to crack it open and look at
the components? :)
