The problem with the charms is probably because the ID for the bags is wrong in the EQUI_Inventory.xml. The ID for the bags are probably all labelled as <InvSlot item="InvSlot0"> while they should be labelled as <InvSlot item="InvSlot23"> till <InvSlot item="InvSlot30">. This should work for all SOD+ installs since they added the powersource slot. Installs before SOD will need to use ID's 22-29. Just be sure to make a backup of the file before tinkering with it
Hunter, You might also want to check out HealdarUI combined with Myxiplx's Tiny Map v2, both of which can be found on eqinterface.com. I believe it's about as minimalist as you can get with all the different parts in easy to move blocks. Though I will say it doesn't have the amount of buttons or as nice a petwindow as the one Xiggie has. Might be a good option for boxing.
