I could throw this open to the larger community, but I'll ask the developers first. Do you have a set of plugins or tasks that you use over and over on new books, sets, or libraries? For instance, do you run Extract ISBN followed by Download Metadata? If I were...hypothetically...working on a plugin to set up sequences of plugins to be run serially, what would be most useful to have linked up?
From my survey so far of the plugins I use, there will need to be a fair amount of customizing to call other plugins, and possibly pass the results of one on to a second, and I'll need the buy-in and support of the creators of those plugins (which in 90% of the cases is Kovid himself, or Kiwidude). But there's no point in setting up the code to work for plugins that don't get much use. So what would you like to be able to launch with one process instead of three?
(I've already setup a framework to poll a user's installed plugins and provide a window to let the user setup and save sequences. All that's left is to code the implementation to actually call those sequences.)
