TL;DRFind should search hierarchically so I don't have to do it manually and I can play the game faster.
What ?There are two places in Factorio where I use search/find a lot:
In both cases, there is a hierarchy (blueprints have books, crafting has tabs). But CTRL-F or magnifier icon doesn't search into the substructure. This forces me to open each tab/book one by one and search within it. If I already knew which tab/book it was in, I wouldn't be searching!
This is especially true of blueprint books, and even moreso for newbie players who are just figuring out blueprints and robots. I often ask stuff like "is there a blueprint to build lasers? robots? modules? plastic?". I've installed several general blueprint books (BobACE, Nilhaus, etc) and I don't really know what is in there, but surely somebody has a nice print for me.
My suggestion: CTRL-F and magnifier always search all crafting tabs, and search all blueprint books. I realize this will make the search results harder to display, because it breaks the nice hierarchy that the crafting-tabs/blueprint-books provide. But it would be so useful!
