 * `player`: required. The player to assign the panel to
 * `position`: the panel position (as in any other HUD)
 * `alignment`: same
+* `offset`: same
 * `bg`: the picture to put in the background
 * `bg_scale`: its scaling
 * `title`: the default text. Default is empty (`""`)
 * `title_size`: (table) as a multiplier, where Y is not considered. Ie. `{ x = 2}` will double up the font size
 * `title_alignment`
-* `title_offset`
+* `title_offset`: if `offset` is declared already, it'll add/subtract the two values
 * `title_color`
 * `visible`: (bool) whether the panel is visible right after its creation. Default is `true`
 * `sub_img_elems`: (table) whatever image to add to the panel
