I suggested this to the MagicStorage mod and they improved it and I think the same could be made with Recipe Browser. If you've ever played Minecraft modded with NEI or JEI, you know perfectly what this is about.

When searching, it would be neat to have tags like in NEI/JEI in Minecraft.
Aka putting a @ would search for a mod (Instead of having a button to cycle through every mod which get annoying trying to find one particular mod in a big modpack). So searching @Magic would search every mods with @Magic in their name.
"#" for tooltips also seems like a good idea.
@modname
#tooltip

If I want to search... Idk, for example sake let say wood but for the mod "ThisIsMod"

I could write "@ThisIs wood" so it will search mods that have "@ThisIs" in it and the item "wood" in it too. Super useful & cool. Much more conveniant and fast than one button that cycles through every mod one by one.
