Inventory Tab

The table in the upper-left contains the list of "Available" equipment. Next to the word "Available" is a selection box that lets you pick which "view" you want. It is this view that will be used to determine the structure of the table below it. The same is true for the "Selected" equipment that lists the equipment your character owns. By clicking on the Filter icons in the toolbar (the icons with the magnifying glasses) you can filter what equipment is included in the table. You can purchase equipment by double-clicking on it, right-clicking on it or clicking on it and then on the right-arrow button. You can purchase more than one item at a time by right-clicking on it. Similarly you can sell/remove equipment by double-clicking on it in the "Selected" table, or by right-clicking on it, or by selecting it and then clicking on the left arrow button above the table. You can also type in a value in the Qty column to change how many of an item you posses.

Carried indicates how many of the items are carried on your person, and thus count their weight against your total encumberance displayed in the Total Weight field near the bottom. A value of Equipped means that the item is not only carried, but also in use. For armor and weapons, being equipped means that any bonuses or adjustments that an item confers will be counted against your character. Thus, if you have an amulet of strength (+2), it will only adjust your strength if you have it equipped.

Location is where you can indicate where an item is located. As you add items to your inventory that are containers this list will include those items so you can place other items in them.

Hand is where, for shields and weapons, you can indicate in which hand you hold it. Primary means that you wield one of the item in your primary hand, Secondary means it's in your off-hand (thus you get the off-hand adustments), Both means you're using it in both hands (for one-handed weapons this means you get 1.5 times you strength bonus) and Two-Weapons can be used when you have more than one of a one-handed item and you wish to wield one of it in each hand. If you have an equipped item in your Primary hand and another in your Secondary hand, or if you equip an item as Two-Weapons, the two-weapon fighting adjustments will be calculated.

The info pane in the lower left will give the details of any equipment you click on.

Capacity indicates the total weight you can carry.
Gold indicates how much gold you have - you can edit this value.
Load indicates what your load is based on your encumberance to capacity ratio.
Total Value indicates the total value of all your equipment
Total Weight indicates the total weight of your carried equipment
Ignore Cost lets you bypass the cost of an item - if this isn't checked, the cost of an item is subtracted from your Gold, or added to your gold if you're selling it.

Masterwork/Magical/Sizing Items
You can make an item Masterwork, Magical or change its properties (like take a regular set of platemail and make it small-sized for your kobold!) by right-clicking on it in the "Available" table and selecting "Create a Custom item". For magical items you need to add "Masterwork" to its list of properties before you can add any magical properties. The Options->Equipment Auto Creation menu item lets you automatically create various kinds of items when you load your sources (thus, if you change this setting you must unload your sources and re-load them for them to take effect).

There are "sliding dividers" between the equipment tables - you can click on this divider and slide it back and forth to your preferred location. There's also a divider between the upper-tables and the info sections below which you can drag up and down to change the viewing area of each. There's another divider between the info sections. This combination of 3 sliding dividers is common to most of the character-related tabs to allow you to change how much screen real-estate is devoted to each section. On most tabs there's a button which has 2 circling arrows that will reverse the orientation of the views between horizontal and vertical. This gives you many options on the layout of the tab.
