Table of Contents
Quick Menu
Minimap
World Map
Options Dialog
Zone Rematch Dialog
Report Dialog
Search Dialog
Node Editor
Quick Menu: Allows fast access to basic display filters (minimap, world map, herbs, ores and treasures) as well as access to the statistic dialogs (see help pages on Report and Search).
Clicking on the menu title will bring up the configuration dialog.
The menu is accessed by the minimap Gatherer icon or though a binding (unconfigured by default). .
Minimap: The minimap will display icons for the closest gathers (25 max, according to filters, number of gather to show, max distance to consider, etc.).
Mousing over these icons will bring up a tooltip detailing the gatherable name, the number of time a successful gather was performed there and the distance to it from current position (in units and time to get there in a straight line at standard running speed). .
World Map: The World Map will display icons for all gathered items in the selected zone (500 max, according to selected filters, etc.).
By default the items are shown (there is a toggle in the Globals configuration dialog tab to display a "Show Item" button at the lower-left corner of the World Map in order to quick show/hide nodes on the world map)..
The World Map also allows access to the Node Editor to do some basic manipulation on the Database, by alt-right clicking on a node. .
Options Dialog: The option dialog is divided in 3 tabs: Filters, Globals, Quick Menu
Filters Tab deals with filters related option (including control for the Show/Hide button on the World Map).
Globals Tab handles options related to core Gatherer functionnality (most of these are also availale though command line).
Quick Menu Tab controls the behaviour of the quick menu from the minimap icon (including icon position and show/hide control).
.
Zone Rematch Dialog: This is mainly a facility for localized WoW clients in which the zone name translations were not complete by the time of the official WoW release.
When zone names are changed, zone indexes change too because they are sorted alphabetically. This facility provides transition matrixes to fix these indexes by selecting a Source Zone order (ie. previous one) and a Destination Zone order (ie. current one) identified by the WoW version and prefixed by WoW client language (the fix item checkbox allows item names that have been changed to be fixed).
This also allows global manipulation of the database, such as changing it's format, this is done with any selected source and destination zone order, for non-localized clients an identify matrix should be used (ie. same source and destination order).
Database is modified, a confirmation is asked but keep a backup of your data, just in case. .
Report Dialog: In this dialog you can display the items you have collected in the various zones (one zone at a time) for a quick overview.
You can click on the various column headings to sort (and reverse sort) the display according to that column contents.
Most of the columns are self-explanatory, except for the ones detailed below:
Type %: Percentage of the ressource compared to number of recorded gather of the same type in zone.
Density %: Percentage of the ressource compared to number of recorded gather of the same item worldwide.
.
Search Dialog: In this dialog you can specify an item and display the various zones in which it has already been gathered.
You can click on the various column headings to sort (and reverse sort) the display according to that column contents.
Most of the columns are self-explanatory, except for the ones detailed below:
Node %: Percentage of the ressource compared to the number of nodes in zone.
Density %: Percentage of the ressource compared to total matching nodes worldwide.
.
Node Editor: In this dialog you (alt-right click on a node in the World Map), you can change the node name, it's icon, toggle it as bugged or delete it.
Toggle Bugged will only work for the current selected node.
Delete use scope (Node by default to avoid mistakes) and can be extended to Zone, Continent and World scopes.
Accept will take into account the new node name (remember to hit enter after filling the new name) and/or icon. As for the delete button, this one takes scope into account and can be applied at Node, Zone, Continent and World level.
Database is modified and no confirmation is asked, so keep a backup of your data, just in case.
