The update of product variation is indeed blocked by the lack of search or sort in variations and for this
I have logged a feature request for this, here
is the feature request in PITS.
To perform updates to variations in batch I can recommend creating a query for product variations using product variations API
A custom control that can be placed on designated backend page created from Administration->BackendPages to support managing variation updates. One way is to enter variation name in textbox and apply logic to update all variations of this type applied to Book products or else.
Additionally, the front end product detail cascades the variation dropdowns and loads them odd. Post backs and losing the options in attribute 2 and 3. Just shows select and the selected option once picked. If you want to change your choice, you have to click select and wait for the post back for the dropdown to rebind.
The inability to save the variations in ViewState of the page is to assure no incorrect addition of incorrectly configured or previously configured set of variations will occur. If needed to have the variation be saved in viewstate of the page custom variations control needs to be implemented to support this, if this persistence of selected variations is needed please let me know.
I am failing to understand the below question to properly address it, can you elaborate additionally on it?
Also lost ability to show price differential in the dropdown itself, since it's conceivable that all Sizes aren't the same price diff. But what if they are, the only solution would be to not show it and have the label populated once picked, put the info in the product description, or setup the variation text with - $20 or + $20 in the title. If the price changes, one more field X 57 to edit.
When there is a variation for lets say different sizes and color and the variation combination is Color: green Size: M this and this variation increases the price +3 $, however having the variation Color: green increases the price + 5 $ and the variation combination doesn`t present a sum of single variations, but renders a set of all variations selected which either disables variation selection dropdowns which are not relevant to current selections.
