Auto-seed/harvest with Shift-select works great for normal crops.
They should also work great (or at least a lot better than its doing at the moment) for trellis setups ... that are not just your standard trellis (single row deep) column setup.
What is, or are the problems, getting it to work better for:
- Two or Three rows deep (in a longer column setup) ?
- Single column (or row) of trellises at 45° ?
So far it seems that after auto processing a trellis there is some additional exit action(walk) that generally breaks the auto-seed/harvest process (as in making the heartling walk into a blocking trellis)
Additional placement options are nice from an artistic point of view ... but make no sense if there going to break production features of production objects.
