This is by far the best tool for tracking all of my characters, their currencies, quests, etc. Huge props!

Looking back there is no less than 10+ requests for this feature, but I don't think any of them explained the request completely. There is no other addon or website that I have found (since MAM was discontinued) that shows all of your characters and their item levels next to each other. I know you can mouse over each of their names. However, if it was broken out into a separate line, it would make this addon that much more valuable and convenient. This would allow players to see where they need to focus their attention / resources (which is the brilliance of this addon!).

Could you please add a line in the window popout for each character's item level (ilvl)? For example:

If anyone else stumbles onto this while waiting like I did. I was able to add it to the display by simply modifying line 4256 in Core.lua to:
tooltip:SetCell(headLine, col, ClassColorise
(SI.db.Toons[toon].Class, toonstr .. "\n" .. "(" .. ("%d"):format(SI.db.Toons[toon].IL or 0) .. ")"),

In case others need this:

Change worked for me! Thank you!

Change is still working for the TWW Prepatch
