BarVis 1.0.0

First public version. WoW Forever only; requires EllesmereUI with its Action Bars module.

• Set any action bar, 1 to 10 or all of them at once, to Show, Hide or Mouseover. BarVis
  writes EllesmereUI's own visibility setting, so the change sticks across reloads and
  matches EllesmereUI's options.
• A small window: pick a bar from the dropdown (1 to 10, or All) and click a mode. The
  line at the top shows that bar's current setting; with All, the setting every bar
  shares, or "mixed".
• The window opens with /barvis, a key binding (Toggle BarVis window) or the minimap
  button, which can be hidden from the window. BarVis is also a LibDataBroker launcher.
• In chat or a macro: /barvis show|hide|mouseover N, where N is 1 to 10 or all.
  /barvis help lists the commands, and Tab completes both words.

Requires WoW Forever and EllesmereUI with its Action Bars module (tested on 9.6.1). Download BarVis.zip below and unzip it into Interface\AddOns.
