A bit hard to test this mod by yourself so I have edited post after talking to one person using the same mod.
The "Reset Entire Database" button, when and why is this required?
I also had a blank browser window and thought someone maybe reset the database so I added a couple of my alts skills and tried it myself.
I reset database and it reset to blank browser until I added my alts skills again.
I asked another guildie who is running older client as they still have the refresh cache button
and they can still see everyones skills, I can see other peoples crafts only when they update again
so is there a way for me to refesh cache without making everyone update?
As you know this mod is only as good as the information people put into the database.
Sort by required level - This doesn't seem to function as you intended.
I dont want you to add new stuff before the current stuff is working as intended but maybe a tab to show who is using the mod in your guild and what trade they do. Atleast then I can message people and ask them to update client/trade skills when required.
