<p>this document will eventually contain a proper documentation, however for now, you gotta live with a few random lines:</p>
<ul>
  <li>left-click items to mark, and right-click to unmark</li>
  <li>you can click most marked items multiple times to raise their count, and decrease the count by right-clicking</li>
  <li>for some "items" (levels, damage spell, heal spell, attack buff), you can middle-click them to change the item to a finer description</li>
  <li>you can switch the position of characters by click-dragging one character onto another</li>
  <li>you can middle-click characters to change the character to one not currently present</li>
  <li>you can drag characters onto items to indicate their equipment in the jelly fight</li>
  <li>you can zoom in and out a few steps with the plus and minus buttons; the smallest zoom level is the identical size to the existing tracker</li>
</ul>
