--Overview 1
(1) Show the settings menu
(2) Enter the pack name you want to save. Right click to pre-fill with the curerntly logged in character name, with a "_" suffix.
(3) Save the pack name. If no pack name was entered at (2) but a pack was chosen at (4), and thus the selected pack name is shown at (6), the pack name will be the selected one.
Depending on the selected save mode in the settings (global = default / save per character) the saved pack will be either saved globally or for your currently logged in character.
A dialog will ask you to acknowledge, or abort the save. The dialog shows you if the pack will be saved globally (light blue) or for a character name (golden).
(4) Select a saved pack from the dropdown list. Depending on the settings you are able to see and select the globally saved and/or the per character saved packs. Character saved
packs are shown in a submenu (character's name).
Per character saved packs do not provide any submenu. Clicking on the pack will load the pack.
Globally saved packs can have a submenu, depending on your setttings, where you are able to select the pack, select the pack and reload the UI or delete the pack.
Clicking on a global pack main entry (no submenu entry) will load the pack.
(5) Delete the currently selected pack (6). A dialog will ask you to acknowledge, or abort the delete. The dialog shows you if the pack was saved globally (light blue) or for a character name (golden).
(6) The selected pack label. Clicking the line will update the pack name (2) editbox. See further details about the (Global) string at (9)
with the selected pack name.
(7) The search box. Enter a search term and press the return key to search for an addon. The addon list will scroll to the addon found. Press return again to search for the next addon.
You can enable different search settings like a search history storing the last 10 search terms. Right click the search box to show a context menu providing the search history, and a "clear histoy" entry.
(8) The count of addons currently enabled/total
(9) The selected pack label, and the save/delete dialog, show either the "Global" (light blue) text if the pack was saved globally, or the character name (golden) of the pack if the pack was saved per
character. If a pack was deleted the selected pack label (6) will be cleared and depending on your settings either "Global" or your currently logged in character name will be shown.

Light blue rectangle: These 2 buttons are added via the addon "Votans Addon List". I recommand installing this addon as it enhances the addon manager with different helpers:
-Automatically enable dependencies (libraries, other addons) if you enable any addon
-button to scorll to libraries
-button to scroll to addons
