I miss the abillity to use absolute offsets. Mostly for $voffset, but occationally for $offset as well!
My config uses the whole screen and I try to keep the TEXT section modular (in several files), as I somtimes makes changes to this section through external scripts. my current sollution is that each section ends with resetting the voffset by printing a '-' just above the first visible pixelline.
On a side note it would be nice if Conky was a little more smooth when rereading the configfile, It seems like Conky more or less does a complete restart. Maybe checking if window-config (own_window, window dimensions, allignment, etc.) have changed before redrawing the window could solve this.
