Hi, thank you for the post!
For us, it is essential that we focus on the most important suggestions and changes, and leave aside the things that are not as important, thats how we make users happy the most!
1. maybe the window can made a big bigger by default. resizable can work but then you would just have empty area on the right, i think this is not needed
2+6. you can change this in .ini files in resources folder
3. good idea
4+5: you can use the general tab use item by id function for this
7. not possible for scriptsell, because that file changes from time to time
Anyway...I am waiting for what other users say here. Please do NOT make posts like "+1", but tell which of these you find most important. I already am quite busy and as I said before, we want to focus on the most important changes, so I want to see what features many other users need too.
