Moving set of tiles in tilemap
First: Great work with the tool - it's been performing great so far. So far I've created an import-utility for Unity3D and use it extensively for development of a couple of 2D games.
There's another post here mentioning features helpful to use Pyxel for level editing (http://pyxeledit.com/forum/discussion/34/pyxeledit-as-level-editor-custom-keyvalue-data-fields) but more than those I'd rather have the feature to easily move a set of tiles within the tile-map itself.
Let us say I want/need to shift/move a complex shape created from multiple different sprites, or a complete part of the level I'd prefer to select the appropriate tiles within the tilemap and move them rather than having to manually redraw/shift every tile.
