Graphics perfectly match the objects purpose. You shouldnt feel the need to change it. Would be nice if you post a direct download link instead of pageload spam though. Posting your github page twice and not posting a actual download link is a tad annoying
I would suggest using the Advanced Logistics System mod by anoutsider to get full control over the items in your network to monitor if you have enough items to provide with. https://github.com/anoutsider/advanced-logistics-system
