Personally I find programs like the UI Installer, and UI Switcher, and EQ2MAP updater very helpful. Sure they are not for everyone, but for those that want these tools they make things so much easier.
Back in the EQ1 days, I used the Garyik's INI Copier extensively, as many of the Complete UI mods I used required I copied the Author's INI file to my Characters so that the layout was correct. And the Maps well the Maps that were available for EQ1 well many times my Guildies had no Idea how install maps back in EQ1 they would download the map zip file from Mapfiend and then save the zip file in their Map folder in EQ1 it did no good having the maps zipped in that folder. With the tools Ger and Taco-Man have made it makes updating our EQ2 maps, and UI's so much easier.
I wish we had more tools like this back in the EQ1 days. I had to write installers for my Guild for all the EQ1 Map packs, and all the UI's. Tools like these would have saved me so much time and work.
Great Job to all of the Tool Authors.
