hi mahdiyari, I had some idea for steemauto curation trail:

• voting power limit
  setting for trail followers to decide to skip trail votes if their power goes below set amount, such as settings of 80% no matter what trail leaders do they will only vote whenever they are above 80% vote power instead of needing to recharge.

• scaling ratio for default setting
  follow leader vote weight is a cool feature, but for some big voters maybe doesn't work as good, so it could be a feature to have an addition to this setting as a ratio such as 1:4 if they vote 100% follower with this setting votes 25%, if they vote 20% follower votes 5%. Better way is maybe just setting as percentage rather than ratio, but either way it could be useful.

just something to consider if you need ideas for a future upgrade, keep up the great work ^_^
