Hey Donni, thanks for the suggestions again!
Both buttons and plant templates are on the to-do list (see 'Foliage elements' and 'UI elements'). The page on Kenney.nl has been updated with some new screenshots and information. Workspace color selection is already on the board (see 'Settings'). I will start doing videos once all features are in, otherwise I'll need to keep updating the videos.
Currently the main menu will remain as in 0.1.2 until the main component (sandbox) has been done. But I do agree that the axonometric creator and the other components have to return/be created.
