There seems to be a bit of confusion on how the user interface works in VOBMerge 2.51 Remixed. Yes, you can rearrange files (click to the left of a row, drag & drop!). Yes, you can multiselect (just click on a row and drag to select!). Yes, you can remove files (just right click, choose remove/clear all).
It's really that simple. No need to complain. ;)
