Hi Michael,
Thank you very much for your feedback, it helps me a lot.
1. Indeed, I will correct that.
2. Yes, that is intentional, as percentage height in this context means ‘in relation to the container’, but the container height is not fixed, so it would be 0 all the time. I am working to implement a way to allow % values relative to the item width/container width.
4. I believe this is due to a mistake I made during the implementation, where the tablet height value is actually reset to 200px. It was reported a bit earlier. During the copy/pasting 1 character was not selected, so a non-existent option is parsed, and the plugin resets it back to default, which is 200px.
5. This was the case in earlier releases, but in a recent release I fixed this, so that the isotopic container does not need to reset anymore on orientation or window width/height changes. You also mentioned that the info box message is incorrect in some cases, which is mostly parsed from item visibility. I am almost positive, that both of these are going to be related to another custom CSS rule, just like that other issue before.
You can also try the demo as comparision test to see if this behavior exists there, but I am almost sure it shouldn’t.
Do you have by any chance a collection of the custom CSS rules you use in relation with Ajax Search Pro? If you do please copy/paste it here or to a gist file, and I will test them to see if they cause any similar conflicts.
