(PS: Since I just mentioned "Create by Name", I really wish there is a function that allows me to create an object from another mfa by name (and mfa path), without importing it to the main mfa.)
While in Global Events (Event List Editor), when you change the name of an altVal or flag to a longer name than before, events referencing that altVal/flag don't update correctly (see screenshot). The problem is easily fixed by scrolling or otherwise forcing a refresh of the event. The problem doesn't exist in the Frame Events - just the Global Events.
When you add a create new object or Set position action, and the frame editor is zoomed out, and you click on an object in the frame (to make the positioning relative), then a rounding error, or something like that, often defaults the X and Y fields to 1 or 2, instead of 0.
But this issue has always existed - I just assumed it was a "feature".
I used to think it happened sporadically/unpredictably, but I've recently discovered that it's dependent on the zoom level of the Frame Editor. Though perhaps the behaviour might be different on different screen resolutions, frame sizes, etc.
I know there is a "feature" related to this if you swap to being relative to the Action Point (in the positioning options) where the offset values populate the fields if you originally had set the position relative to the hotspot. I understand how that could be useful, but have never needed it, so it has become more of a burden.
Honestly, things like this feel like awesome options to be able to customize in a global setting somewhere. It might be too late for F2.5, but I hope these minute customizations can be a part of F3.
