Is it just me or are the LastTimeOpened and Added operators backwards? Currently, added>7 finds comics added within the past 7 days. Isn't it more intuitive to be added<7? As in, added less than 7 days ago. LastTimeOpened behaves this way as well and I find it weird that LastTimeOpened<30 actually means comics opened >30 days ago.
Internally is comparing dates and the operands make sense for dates, but since the interval is expressed in days it's hard to figure out what's going on. I am planing on adding some aliases to make it easier to read/understand.
