New version is out, mainly bugfixes. I took a look at the MultiGatherer issue and there is not much I can do about it. But an easy fix is to just increase the delay set in the options. I also increased the default value to 500. If MultiGatherer makes any problems, just set it to 500. This is still fast enough for automated actions, but never caused any problems for me. DungeonLoot displays a little more information now.
The main highlight of this version is the new ExtraGears page found in the AllInOne menu. It should work if loaded from any page, but the gear builder. If it interacts strangely with another page, let me know. So how does this new page work: You click on the gear that you want to overwrite, then you just click on the ExtraGear and it will be saved. It is way faster than the normal gear builder, but can only be used to load ExtraGears, nothing else.
