I know you are not doing any thing with the Gallery till it is moved. So this is for later or now.
The tabs at the bottom of the pages are # 1 to what ever, I know in my case with some coins - example
LMC I have 8 pages, would it be possible to be able to put a date in the tab that way we would know what page to go to if looking for a certain coin.
Hope I explained this right.
