Currently app is really bare bones.
It has following features:
- if you press ctrl+e on almost any item, app opens a window that redirects directly to that type of item mods on poe2db
- in the window it highlights with green outline mods that are already present on the item (IMPORTANT: the limitation of copying items from poe is that affixes that have double lines like for example % physical damage and accuracy and such can not be properly discerned, therefore app just highlights all mods that could possibly be there)
That's about it. I tested the app only on windows.
