NEXXT 3.6.1 - minor improvements & user report fixes.

For the NESmaker crowd, importing nesmaker-style images is now made easier (you don't have to mind where the tile cursor is).
Exporting to nesmaker-style images has both become more versatile and easy. There's now a dialog that gives you all the sensible options you could want; letting you export the portion you want with ease. 

Other minor improvements include configuring the 'sidebar' (tileset, palettes, etc) from right to left if you so wish, a few more options for exporting animated metasprites as code, and a slightly more visually responsive box selection on the tileset canvas.

Other than that, this update is mainly shipping with 8 bugfixes; whereof no less than 6 pertain to 'metasprite to clipboard' actions when used with specific combinations of animation export settings.
