I believe that we get problems similar to DLL hell,
Only if installation of Vcomponents folder is made into some
            __central__ place on computer.

But IF Valentina developer will put Vcomponents folder into app folder,
Then no problems. On the same computer can live SEVERAL Valentina-made
applications and they will not conflict in any case, even if they will use
different versions of Valentina.

IF you SELF will not distribute separate .dlls from Vcomponents  folder to
your users then also no problems.
If you decide to provide your users with some updates then this is up to
you. You can make installer to do that.

As I have see .DLL stay in the Windows folder.

Where you see complexity?
Explain me please.

And I can say we have no other way. Because Valentina 2.0 is SEVERAL times
more complex projects of Valentina 1.x. Valentina 2.0 depend on several BIG
third party libraries.

The main problem that NOT all libraries allow link them, they are build only
in the form of DLLs. For example IBM ICU library or ImageMagic.

Even if assume we can link all in one, then we will get V4RB plugin for
single platform about 12-15MB of size. As you know REALbasic require that
all 3 or even 4 plugins for each platform was inside of single plugin file.
Image the size of this V4RB plugin! Close to 50MB. Yes this will affect only
you Brendan, but not your users.

Although your users also will get always YOUR APP with size
    your size + 15MB of Valentina size.

Although Valentina 2.0 itself is only 3.5MB.

We believe that it is much better to have component based system.
At last of end look around. Where you have see complex systems ALL IN ONE?
Why all big systems use CORBA, COM, .NET ?
Just because when system grow to some level it is not possible and not
effective keep all in one.

Component system in ideal must allow YOU to skip some parts of system which
you do not use. For example, if you not use Pictures, then simply remove
from YOUR Vcomponents folder the image library. If you want VERY VERY small
and simple database without SQL then remove HUGE SQL parser and executor
overhead, remove ANTLR.dll and make Valentina engine 2 times smaller for
your users.

Can you do such tricks if all in one ?


------------
And we believe (hope) that if Valentina will have own plugin system,
Then third party talented C++ developers will be able develop own versions
of fields, functions, indexes, importers, compressors ...

How many people dream about DBF import/export.
But we want not able yet implement it. No time.
With plugin system this can do somebody else.

We believe that OPEN SYSTEM grow faster of closed private one.
And so on and so on.


-------------
I was sure that everybody on this list have told:
    we want better SQL parser
    we want better SQL commands
    more features
