Thanks guys for all the feedback and posts, really appreciate it. Added a few things on the next update list which will be posted very soon. ^^
For mirror mode, it is supported but you gotta make sure it's setup right: stay logged out when launching both clients, login manually, start the script, increase the reaction timer (for combat which is not dangerous). I would highly recommend waiting a bit more until mirror mode is fully perfected by the devs, since it is still beta/experimental.
As for mac saving/loading: any errors in console log? I will help ASAP. It worked for me in linux and it should be the same for mac. Never had any complaints Please confirm!
As for sand crabs - make sure your tile is on the edges. Otherwise where do you want the bot to run to? If you are in the center, no other tile is far away enough to refresh aggro. If there is another way, let me know. How about going off the island and then returning? But it's 10k/trip so it's not worth it.
As for the rest, I have noted down and you will see your post in the next version update changelog, thanks guys
