Hi, Well this one has been discussed to death with the support team [i can hear them all chuckling now at their desks.
Pre "Lightspeed" - (Even the name conjures up the concept of time-saving tips/tricks. It is anything BUT time-saving. Here's one classic example of many I will post)....
.... a sub-tasks header field looked like this. It had the count, and the completed status-bar [green]. See below example.
For a manager, opening a task with a summary of completed sub-tasks is VERY useful - comforting even. if the bar is not fully at 100%, we can drill down with a click.
Now, "Lightspeed" makes a mountain of extra work. Again, UaT fell asleep at the wheel when testing this out. Who's idea was it to take the status bar [green] away ? Who's idea was it to show the user, when you click on the sub-task field/element, the system scrolling, flickering, pull up super fast before crashing to the bottom of the screen and "Description field", then back up again ...?
Why not show the sub-tasks immediately BELOW the bar: like this...without all the scrolling.
Lightspeed has this :
[?] Yes, 7 sub-tasks, but what is the status of each? How many are completed? Again, Lightspeed wastes more of my time , clicking "7 Subitems" to show the status of all. The Green bar did that without clicking, and moving hands off the keyboard and on to the mouse and back to the keyboard. Put the green-bar back !!
 Fields displayed that are populated at the creation of a task/sub-task, and rarely EVER used again by the common-person. Get rid of it, hide it, or better still PUT IT BACK up hte top. The top ribbon bar has a status, Assignee, date - far too much wasted real-estate, that could be re-populated with the same data with is now below wasting more space. Pre-"lightspeed" had this.
So, in 2/3 less space, the old system has the Importance, status, assignee, ID, Created Date and Author. PERFECT.
Lightspeed now spews all this over 1/3 of the right-hand side of the page. UaT - really ??!!
And the new field "Item Type" "Task" - do we really need to know this here ? Maybe I've missed the point with the "New Look". Wrike Dev team - feel free to enlighten me.
So, in a nutshell. Get rid of/hide the wasted system data at the top of each task/sub-task; but leave the CFs - just like it was pre "lightspeed". Show more/less is good, but not for the system data. Lastly put BACK the green sub-task status bar.
