This is solved in Blender2.8, its unlikely we spend time on tweaks here in 2.79 - archiving.

hmm seems nobody else care‘s about....sad

Hy guys , in newest builds eq from 12.06.18

IIRC, Shift-O is currently used for "Sample Keys". That said, maybe we don't need a dedicated hotkey for it (and the Smooth Keys - Alt-O) operators, as I don't think they're actually used that much that they necessarily need the hotkey.

I'm loving the "X-Ray" slider! That certainly helps, dragging that to 0 replicates the appearance of the 2.79 wireframe.

Not entirely UI related, but do you have any plans to remove Hemi type lamps from the add menu and Blender entirely?
They were only really supported by Blender Internal, the old GLSL viewport and Blender Game Engine, which were all removed.
Cycles never really needed those, and were interpreted as point lamps AFAICT, and with the introduction of EEVEE it seems they are no longer useful.

Proposing more efficient edit_mode selecting:

• Currently double_click is not utilized. For example in maya when double_clicked on Edge it can do edge_loop. When on Face, it can do Element select (linked select )
• Ring can be achieved with double_click + modifiers (ctrl/shift/doesnt_matter)
• Ctrl+MWheel could be utilized to grow and shrink selection.
• Border select is also often useful. Areas could be quickly marked (seam, sharp) and then recovered with double_click on face.

How about Shift + I & Shift + O ?

With the sculpt Mode j refer to the drop downs. (Not tablet friendly, only 1 can be opened at a time
I wonder if you are a user of the software because this sounds totally dogmatic and not based on user reality. In cases you are right of course in other places like xyz coordinates or view resolution and frames single column is an utter waste of space. Having to move the cursor to access information has to become less not more....

Also consider this: The speed at which you can locate an element in the UI is not always correlated to the number of items visible at all times. You can have a UI like 2.49, with thousands of tiny buttons, and users then have to play a game of Where's Waldo to locate what they are searching for. Even though you have more items on the screen, it can be slower to use, and require more cognitive load, because they are not quickly scannable, properly labeled or grouped in any consistent way, which adds lots of mental overhead.

We are adding multi-column auto-flow support. Currently it works in Object Properties Transform and Relations panels. Has to be added more places.

Unification for unifications sake seems rather pointless to me. I fear a lot of these changes in 2.8 are very significantly doing one thing. Remove information from view.
I don't care if it's easier to learn this way, once learned the other way isnt hard either! But the other way gives me all the information I need at once. Here the direction seems to be leading away from this.
This especially goes for sculpt mode and the single column direction...

Can i dump all of my tokens here?

• Merge branch 'blender2.8' into ui_layout_gridflow
• Deduplicate some code, new solution to the fixed-estimated-size problem.
• Some more tweaks and cleanup.

seems to be fixed in Blender 2.8.

+1 for a fix on floating windows ^^
