Hey Bagu- I agree, item menus are hard! I haven't figured one out yet either, I literally designed my game to only have two items so I wouldn't need to do one, in my opinion menus are definitely the hardest part of designing in Solarus. My best advice is to start learning by making a static menu- one that will come up and display information, but you can't interact with (a quest status screen, for example) before you get into an item menu. And once you start trying to figure that out, be sure to post a topic explaining how you're doing it so I can learn from you! : )
Ponderitus, thanks for the compliments. BTW, if you want that deku enemy, you'll need a function that has a "check hero" thing every 100ms or so and gets the distance to the hero, then if that distance is >100 or whatever, remain asleep, if it's <100 and >32, wake up and shoot, and if it's <32, go back to sleep. If you want more help, post a topic about it and I'm pretty confident I have code that will work.
