I am making a JEI addon mod that will create lists of items needed to make a specific item and tree views of how to assemble it all.

Would you guys mind if i dig around in the LP code for using the guiscreen to make such a tree view? If not could i maybe get some pointers on where the main code for it is? LP is very complex and not sure where all the parts of it are.

Sure feel free to dig around.
Most of the RequestTreeView is inside this class:
https://github.com/RS485/LogisticsPipes/blob/stable-bc7/common/logisticspipes/gui/popup/RequestMonitorPopup.java

Feel free to ask any questions if you have them.
But be warned, that code is functional but not pretty.

i'll base my code on some parts of it (mainly interested in the GL enable/dissable commands as they can be tricky)

i have some idea's on how to make this a bit cleaner but i'd have to write it first to be sure it doesn't become a huge mess

@AEnterprise this sounds really cool!
