PyxelEdit Tutorial - Basics

Hello everybody! I've recorded a tutorial for PyxelEdit covering what I would consider the basic core functions. You can find it here: PyxelEdit Tutorial - Basics.
I'm planning on creating a few more tutorial videos to go over more advanced features like animations, transformations, gradients, etc. If anybody has some specific requests, let me know. I'll do my best to cover everything! Questions, comments, and criticism are welcome.

You covered pretty much everything, although I think you should've mentioned the offset tool though! It looks like it has a greater purpose in tile mapping.
As for the offset tool, I'm actually a bit at a loss as to what to do with it. I'm actually quite new at working with pixel art and tilesets, so I'm learning a lot as I go. Does anybody have a good explanation of how best to use the offset tool?
An example for its use would be, say, you've made a tile and whoops! It doesn't line up with another tile you've worked elsewhere (it happens!). Just use the offset tool to shift it across and its done.
Or maybe you've finished your tiles for your ground texture, and you realise later that they all need to be adjusted a pixel or two across to accomodate some new changes or to look neater. Maybe you're still mocking-up and you're rearranging how your textures look. Offset tool to the rescue!
Simon: Maybe you could make a more workflow/art focused kind of tutorial? I know you have a lot of experience with the program (probably more than anyone) so I think it would be interesting to see how you approach things!
A workflow/art focused tutorial from someone like @Simon would be brilliant! And maybe you could include some advanced tips and tricks from up your sleeve... I'd really like to see that and to learn from a pro!
