VDC v1.5

1) Can't see a grid to box up the individual sprite, which would make coordinate-finding even easier since I no longer need to refer to the sprite file itself to know where the top left corner is.
3) Minor point: would be nice if you can activate another grid for individual pixels.

I can see how this would be useful right now. Once you can drag around every element within the visual window I see little point to seeing a pixel grid though. I'll give it some more thought, but other things have priority.

2) Can zoom in on the picture, but it always zoom towards a specific point and I cannot drag around the sprite. I have to alter the window size instead.
#2: This is zoomed in. I want to be able to see the head too, but I can't drag the image down or use arrow keys to see the head. Did I miss anything?

Hold space and click+drag to pan around.

While the program can import .dat files with the method Someone else fixed for me, it will for now only save .txt files to prevent you from damaging any original data (LF2 can load .txt files). I may add .dat saving as an option in the future, if I feel enough people have managed to use this without problems.

This is pointless. Doesn't this mean I will have to change the names of my .dat files in data.txt to end with .txt instead? While it might be good to have a backup, it would only work the first time you save it, and then you'd have to open your newdat.txt and the backup "feature" is gone. It also means that I can't assign the program as my default editor for my new data files since they're .txt now, and I do want to have a datachanger open my .txts for me.

Yes, but it's not pointless. The editor can natively import/open .dat files. The point is you cannot save over .dat files so you cannot damage them. Everything you work with in .txt format and this editor is obviously in danger of being scrambled by whatever naive programming mistakes I made (happened to me once on another editor - never using new tools without backups again).
I know directly assigning this is useful, and you can assign this editor to .dat files. For .txt files just drag them onto the program to quickly access them for now. I want enough people to properly test this before diving 100% into using it all the time.

Other than that the encryption also seems pointless to me and I'd love to fly without whenever I can. A unique file type is another thing, sadly LF2 seems to only load either .txt or .dat.

In short: please try to crash it, break it, make it fail at any task you can think of throwing at it. And report back with detail.
