813079 - Edit Mode. Need to increase responsiveness when dragging icons around page and moving them through pages or to dock

Status: RESOLVED FIXED

Description

[Pablo Sanchez [:pabloUX]]

* Environment: Unagi, Nov 16 dev. build. 
* Repro: navigate to Home. Tap-hold icon to enter edit mode. Drag any icon around page, to dock, or through pages.
* Expected: Entering edit mode, there should be a fluid response to user dragging icons around page, when included in dock or when moving to new pages. Icon behavior should follow users finger and grid should rearrange accordingly (including creating new pages)
* Actual: Dragging icons in edit mode are cumbersome (takes finesse and several tries to move them). If gesture is quick, UI moves to change page, not to move icon.

Completely agree. Current Edit mode is very unresponsive, bordering on hostile to user. Should fix for release.

Cristian, is this just a matter of tweaking a few timing variables?

Gordon, can you look at fixing in the UX branch?

Removing the "uxbranch" label after talking to Gordon. Need info from Cristian on level of effort required to fix.

This should be reopened. The issue is present in v1.4 on ZTE Open: I have a very hard time moving app icons from page to page. Even when I manage to push the icon more then half way (which is hard due to the size of the finger v. screen) it still doesn't go to the next page. Most of the time when I manage to drag an icon to the page on right the scrolling is so fast that the icon ends up on a new page!
