The calendar is bulky and tough to look at. I suggest a timeline view where you can click various options like "batches brewed" and it shows on the timeline all the batches done in a sequence by date brewed. Or another option for "brewing improvements" and I can see where I bought that new temperature controller, or started using pure 02 on my batches. Or another option for "$ spent on homebrewing" which shows money on a time line for ingredients or equipment purchased with an option here for tally by month, year, week.
