It would be interesting the gauge component natively in Lazarus. The
gauge is a nice and faster progress indicator. We can create it using
tshape, or anything that shows progress without "flicker" (I use
doublebuffered to solve flicker in progressbar ¬¬' ).

Please see this comparision:

I don't know if the Lazarus team will accept the gauge component
natively in the Lazarus, but it would be very interesting a component
of this type available after installing the IDE. ;)
