Used photos sync to OneDrive for quite a long. Every time I want to access specific photos to look/show them or download them, I can not do that.
I don't want to sync gigabytes of photos to my laptop automatically. wasn't it the idea to keep everything in a cloud?
But onedrive photo sync (from the phone) is more about uploading but not then accessing!
1) I cannot open more than a few days in a browser (it just will stop loading the page, cause thinks the list is too long),
2) I cannot filter photos by location or date.

So how on Earth can I show my photos from my last vacation?

So if you had options to filter photos (from the camera roll specifically) by a date range and location (coordinates + city + country) and then allow to work with them (open and list one by one, select, add tags, etc. as well as download the results in one file), that would definitely solve the problem and make your cloud actually usefull and not just misleadingly useful.
