Cursor Focus Retention
When going through my cards and adding them to my collection it would be useful if the cursor would remain in the last search bar (Main/Card Number) used when the new page loads.
In this way I can easily leave my mouse hover over '+collection' instead of moving back and forth across the page for each and every new card I want to search for.
The page refresh automatically places the cursor in the MAIN search bar, which is fine when sorting through misc unorganized cards.
This is a useful feature for when cards are organized set but not numerical.
That makes perfect sense. Thank you for that thorough explanation. I can see why you'd want it in the same field so you don't need to click on that field for every card in the lot you purchased.
If you are clicking on "+Collection" button on each card number page, the cursor will automatically leave the card number field. That is a browser default behavior. It would be technically possible to move the cursor back to the card number field after clicking somewhere else, but that might create unexpected problems for users if a particular user is not expecting the cursor to move back to a different field (since that is not normal behavior for browsers).
I probably can't implement this at this time because of the potential downsides for users. Sorry.
