Since I'm working hard in Pixteem, tough it's still in alpha phase it has advanced. Here are the lists of improvements.
- Window resizing will no longer destroy the image.
- Predefined colors toolbar.
- Grid is hideable.
- Now you can draw a single pixel without need to move the cursor.
- Server implemented for exporting to png in a default 3x scale.
- And of course: you can export to PNG already!.

I will be pushing forward to do a nice pixelart tool. Thanks for all the supporters.
