1. Add combat calculators (With a large variety of monsters)
2. Add Sacred Clay/Stealing Creation Tools
3. Add target experience
4. Be able to enter your current level
Agility1. Add the advanced courses
2. It looks like for the Yanille course you have each and every obstacle, while for the other courses you don't. I think just the complete course is fine.
Construction1. No suggestion, but I'd like to say that I love the layout of it.
Firemaking1. Barbarian firemaking needs to be added
2. Pyre ships need to be added
3. Add logs in fireplace
4. Add fixing the Dorgeshuun light bulb
5. It would also be nice if you could separate some stuff into different categories so they're not all clumped into one list. Perhaps you could separate into categories such as: logs, pyre logs, barbarian firemaking (Not exactly sure what it's really called), and other
Fletching1. Half-bows need to be added (See
below)
2. Things such as stocks, attaching limbs, and stringing need to be added for the crossbows(See
below)
Hunter1. You may want to rename the category "Impetuous Impulses" to "Implings", as I didn't realize that both the maze and non-maze implings were there.
Prayer1. It would be nice if all of the altars could be added, not just a gilded altar
2. 1 and 2 incense burners need to be added
Smithing1. All of the actual items that you can smith need to be added
Summoning1. Summoning Familiars needs to be added
2. Ability Scrolls need to be added
3. Not a suggestion, but I absolutely love how they're currently separated by charms.
Thieving1. Sq'irk juice needs to be added (See
below)
Woodcutting1. It would be nice if you could separate the logs and canoes into different categories
It will be nice to have non-Java calculators.
