Viewdraw, or as it is called now Pads/DX Designer is not that much better

Up to P99SE the simplicity of the Protel user interface beat Viewdraw or
PowerLogic (which I used from DOS version also). I have only used Protel
since P98 came out, but used Orcad since SDT IV / Powerlogic since P2000 /
Viewdraw (hated that, gave up)

With DXP Altium decided a more cluttered environment was in order and
spoiled that simplicity a bit IMO not only for previous Protel users but new
ones as well. I think it was haste, or developers with a new toy (nice
panels)  and a little additional razz for marketing but I have a feeling the
comments on the DXP list to rationalise the functions within the panels to
tidy them up and reduce the amount open at one time will get a fair hearing.

It is far more natural than you think.

No one usually bitches more about DXP as regards the UI and project/file
management structure than me.

But as far as comparing Viewdraw and DXP, I would have to pick DXP every
time, warts and all.
