I’d love to see the ability to add usage dates for inks that don’t require the entry of a currently inked pen. I use a dip pen when I feel like changing my ink up in my journal but don’t want to ink up a regular pen. I can’t find any way to track just the usage of that ink by date, separate from the pen itself. It can have an additional field to indicate the pen that was used, but the ink usage date itself is the priority for me. With over 500 inks in the collection to choose from I want to not end up using the same ink multiple times while skipping others altogether.
