If you align value items to left or right it does not work in longer period of time.
The items move depending on digit numer displayed (attachement VALUES):
1. Good to have option set decimal digits,
2. Good to have option TEXT SIZE,
3. Do not change VALUE ITEM size dynamicaly - let me do that by options.
While we appreciate the interest for this suggestion, we have decided to decline this item in favor of other high priority work the product needs. Thank you for your feedback, and please continue sharing suggestions for how we can improve PI Vision for you!
