 ==== BUGS ====
 
-merge registries; prevent creation of variable with name already used by function
 
-==== New functionality ====
+==== IMPROVE EXTANT FUNCTIONALITY ====
 
-pipes to avoid unnecessary files: oy y/[].mr{abs(x)>7}.oy{y^2}.avg[j] ?
+merge registries; prevent creation of variable with name already used by function
 
-splines (e.g. to approximate measured resolution)
+coord name algebra
 
-convolution with function
-- with spline
-- with TOFTOF model
+handling of inf, nan
 
+dp: output for #spec>1 is obfuscated
 
-==== Improve extant functionality ====
+fs: for curve-calling-external-program (cc ecr or similar)
 
-coord name algebra
+mfj: remove redundant doc lines
 
-=== plotting ===

 "update plot" to replot after change of axes

 ==== WISHLIST ====
 
-customization
-- let user choose points/line
-- let user choose color/symbol/linestyle
-- debug mode (e.g. gnuplot monitor)
+splines (e.g. to approximate measured resolution)
 
-allow ad-hoc addition of fit functions
