not sure I get why pulling it out would solve anything for professionals 
- what behavior would they expect IF they are still allowed to overlap 
regions then? I would expect a mix of regions when overlapped - no? and 
if they do mix why not have them cross fade instead of doing a 
butt-splice mix?

sorry for rehashing all this - I know I'm late to the Ardour3 party and 
everyone is grumpy from overwork :\

right, some audio editors used to have a feature called "paste mix" 
which was also apparently of "no use to professionals" and why it's no 
longer found in mot editing apps - it was a very useful prototyping 
feature not found in the beige vanilla audio editors commercially 
available (Audacity also lacks this btw)

but yes the cross-fading overlapping regions was unusual and was part of 
what made Ardour2 a cut above the rest IMO

I'll stick with Jack2 for now - I find that when I start "solving" 
problems like this in Linux audio new and bigger ones emerge and I can't 
afford the downtime in the studio right now

OK - is there a bug list I can look at?

do clarity and power have to be mutually exclusive? I find that 
confusion in a UI leeches any potential power

for example: IIRC there wasa  tab called Redbook but I wanted to add one 
that suited how I work, so I added a tab and proceeded to edit it, I 
called it 44_24, so the new tab was created but it also replaced the 
existing tab that was Redbook with a duplicate of the 44_24 one just 
created so I wound up with two tabs called 44_24
> We would welcome suggestions on how to simplify it/ease its use.
good to know you are open to suggestions - I just want to be able to add 
a new tab then modify it with the various params I typically use for 
audio - it seems like it's almost there - it's just unclear exactly how 
to do this

not that I could see and why I tried to add it - I would expect that the 
user could add her own tabs with format/resolution/bit depth params for 
ease of workflow - is this not how its supposed to work?

I saw that -- but there was no indication elsewhere (that I could easily 
find) of how export should work

that's a shame since it made working on quick and dirty sound design 
prototyping very easy - I guess I'll just have to use the fade-in 
fade-out handles and kludge my own cross fades then :\

I understand I'm walking into conversations and debates that have been 
raging for some time now and probably everyone is sick of rehashing for 
people just migrating to Ardour3 now but I have been a evangelist for 
Ardour for years and a monthly subscriber now and would hate to see it 
become a design by focus group tool that is useful to people cranking 
out pop records and film soundtracks only (aren't there enough tools for 
those people?) - the thing that made Ardour killer is how simple and 
intuitive it was to use and how some of the features could be found 
nowhere else - I I like where Ardour 3 is headed but I hope you don't 
throw out the baby with the bathwater by killing all the charm of Ardour 
2...which is the version I'm rolling back to for now as Ardour 3 doesn't 
seem ready for prime time. :)
