Make a tab / notebook interface.

Allow user-extensible settings (new tabs).

Settings for: decorations etc. superpose (lattice) layers?

Dialog not modal.

Create the dialog once (after plot is initially drawn?) then just fill it in when it is opened. (currently way too slow to open)

For lattice plots, make a tab for modifying theme (via simpleTheme) col / col.points / col.line alpha / ... points: cex / pch / fill / font lines: lty / lwd polygons: fill / border (vectors for superposing, only first used otherwise)

-- this could be a stand-alone tool for creating lattice themes -- (save to global workspace)

lattice only:

all settings in $scales! (relation / alternating / tick.number / at / labels / rot / format (POSIXct))

handle main etc as vector or list -- or grob

layout (cols, rows) or (0, n); as.table

index.cond function

strip style...
