filtering pictures on date is only possible from the search menu (left side tool bar), this require to create a filter and enter the absolute date.
1st probleme in the advanced search :  the relative date like "today", "yesterday"  ... is only used to enter the absolute date , but it is not possible to create a search like (pictures modified today) that can be used at any time. Each time you would like to use search filter , you have to update the date in the search

2nd suggestion. as said the only place we can specify the date is in the advanced search. Now it could be very usefull to add a new filter item in the right side tool bar dedicated to the search with relative modified or created date (today, yesterday, last week, last month,...). For exemple , you are looking at all the pictures that have a specific tag, but you just want to see those which have been modified today, that could be helpfull
