I'm looking forward to this one because I'm currently using Hort and it is such a pain in the......
A few ideas I had for you:
1: Hort will retire plants, but it will not move the bowls to a designated container. Instead, it will drop them all on your character and then to the ground once your backpack is full. Perhaps there is a way that it can be coded into the script to drop said bowls onto a bag and ask for a new bag when the current one is full.
2: Hort is capable of gathering seeds and resources, but it has a problem that I've noticed. It tends to retire your plants (if selected) when the seed count reaches 0 on the plant, not how many are left for the plant to produce. Example: it will retire plants with a seed/resource count like this 0/2, 0/1, etc. I didn't try to retire any plants prior to 2 seeds left, but some of my plants were at 0/0.
3: Hort gives you the health statistics and potion use statistics for your pants, but it will not do the same stack over without being restarted. Also, I believe that it would be helpful to many users to see where their plant growth is. If there could be a chart that tells us which stage are plants are in, I think it can help a lot of people. Perhaps in two sections, mature and immature plant. Immature plants range from stage 1 to stage 9 and mature plants range from 1 resource to 8 resources.
4: I know that this one should probably be a separate script, but I feel I should mention it. An add-on to cross pollinate certain plants only. Have a drop down menu to select your first plant and another drop down menu to select you second plant. Then, it finds said plants and crosses them. It does this for as many plants are available. I know that this one would very complex and difficult to produce and if I could write scripts, believe me, I'd be helping you as much as I could.
Anyway, that's all I've got for now. Hope to see this bad-ass up and running cause I'm getting really frustrated with Hort. (As if you couldn't tell)
