The Advanced Sequencer is incredibly powerful, but I find myself wanting to use the same values across targets. For example, if I’m shooting multiple targets in a night, I’ll need to go into each and ensure the temperature is set the same in each. Generally, I’m shooting the same exposure time for each, so I’ll set the exposure time and dither frequency in each.
It would be great if you could specify the variables in the beginning and then be able to reference them later in the sequence. Instead of setting exposure time to “300s”, you could set it to EXPOSURE_TIME.
For bonus points, you could even have variables that are computed from other variables. For example, if I want to dither once every 15 minutes, I could set DITHER_FREQUENCY = 15 * 60 / EXPOSURE_TIME
(and then some way to round that to an integer).
Much of this is already implemented in the Constants for Exposures plugin (# exposures, exposure time, dithers).
