Can you say why?
The updates is made to make OpenIV better and fix critical errors as soon as possible. Instead of Spark it's still updates and gets new features.
OpenIV have support of EfLC since 0.9.1 version which was released a long time ago.
OpenIV have much more features than Spark, it's because it's need longer time to start. And BTW when I click on EfLC or IV icon in Spark it takes the same 4-5 seconds or even more.
Maybe so, but how often you rebuild archives? Really when you use OpenIV you no need to rebuild archive every time.
Spark is user friendly? You are kidding? Where?
Just think OpenIV is allow to use drag-and-drop feature between OpenIV and Windows Explorer. Drag-and-drop even work in OpenIV's Textures editor. Spark don't have drag-and-drop at all. OpenIV is allow you to create new archives, Spark no. OpenIV's Textures editor is the most powerfull texture editor for IV now, with it you can do anything, even change compressions and mipmaps.
Why is too advanced to do all modding with? Why you using two apps when you can just use one tool for all.
Yes, it is true. But this is just one feature which have Spark and OpenIV don't have. But OpenIV have many other features like modes viewers, search tools and openFromats with is much more then audio editing.
