Blueprint Janitor
This was previously in the before-times an exceptionally simple mod that de-cluttered blueprints from your main inventory (but not the quickbar - NEVER the quickbar.)
But now, in the now times, it is not at all what it once was. Now it is different.
A button you click that requests items from the logistic network for the blueprint you're "holding". EZPZ.
Please check out my other addons as well! For example Tidy Pls! or Shuttle Train Lite.
LOL
So, for those of you (like me) who had no idea, the base game kind of has this functionality already though not all of it. Please read https://mods.factorio.com/mod/folk-janitor/discussion/6730ad79b190dc0e5225601e lulz
