For blank space to the right; Could that feature be exposed as a chart parameter? The user could then simply use a slider from the standard parameter dialog to alter the number of extra bars.
A parameter is not as immediate (i.e. requires more clicks) as the scrollbar approach. But, that is also its strength (i.e. becomes an explicit operation rather than unintended side effect). Additionally, it would be nice not to force a context switch (i.e. change symbol) just to reset a value. Context switch breaks the train of thought. A parameter setting would allow the user to stay within the same context at all times. Continuing with that line of reasoning, it seems to me that the extra space would be desired on a chart by chart basis, rather than a symbol by symbol basis. In other words, it is the nature of the Plots that require the extra space, not the symbol. I would expect to want the same extra space when iterating through any number of symbols on a chart. Finally, as a chart parameter, changes would be local to an individual chart vs. a preference that globally affected all charts. In other words, a "maximum" preference only reduces the symptoms, it does not eliminate it. One chart's desired maximum will likely be different than another's. Admittedly, I have not looked at the feature yet. I'm basing my comments on what has been posted so far. So, I apologize if these comments are not applicable.

With 10 layers above and below, I could have enough layers to make my functions truly modular. > > I absolutely love that the default study lines are below the Gfx plots.

A way to select colors by stepping through values in a way that makes sense to the eye.

Though I must not understand what you mean by blend between the background. I changed chart background colors and it did not change the color of the oval I was testing... Wait, I just figured it out. It uses the color of the background when you create the object only and does not change it dynamically after that. > > > Blank area past last available quote can be now enlarged on the fly by simply using > arrow in the scroll bar or using mouse wheel > > > This one is causing me some difficulties.

I move left to see some last support level for setting a study point, then I give the scroll wheel a quick zip to get back to the right default position again for trading the current bar. With this new mode, I zip right past all the bars to a blank chart and am lost in white space. > > > So this feature is causing me more problems than not having it at all.
