Keep it the same. Dont Remodel !
Acronis used to have a really nice program I knew how to use it it made sense I had all the bugs worked out they became successful they decide to redo the whole thing. I dont use it. Same thing happened with ACDsee photo viewer it was perfect it did things I loved again they had to remodel it change it make it new and improved now I don't even own it. I think if you want to make changes do it in a plug-in way and never Force changes on people. The program is valuable because people know how to use it so pls never make that just flush away and thinking that you can do better. It's kind of like the little store on the corner of a Backstreet. It becomes one of the most popular stores in town and they decide that they need to move it to Main Street then the next thing you know they're broke cuz nobody likes their new store.
I had to pay for more libraries.... but you did not
do a make over... you did not make it new and underimproved unfamiliar. Its so common for folks to become egodriven control hungry greedy and top heavy. The temptations to show people whos Boss is overwhelming and its what destroys good software.
