3D Cursor is confused with the mouse/tool cursor, and it's more like "marker", "reference point", "pivot" than "pointer".

Select Circle, its action is more like a "Paint Selection Tool" than select circle, (it looks as if it acts similarly to Select Border).

I also don't like "Grab" and G-key, and I use D-key (drag) instead and G-key for Grease Pencil.
The "Move" is much better.

You need to attach your .blend file.

As said before T54930 we would need more information.

This addon is not maintained by the Blender project, so for issues you should report to the authors of that addon.

Actually, there is a lot broken links.

...and it seems you have a problem with the mesh (too much subdivided, overlapped, check it out first).

Tris: 2,888,816
Mem: 3764.28

The cloud icon above the text field, drag-and-drop also works.

You have some selected area, in your case it's one element but can be any number (it is the previous selection area).
Then you perform Pick Shortest Path and it adds a new selection.
The previous selection should remain unchanged, i.e. first face in your case.

Try the "Open in Low Resolution" option.

Can be said simply:

Looks like this T56175.

The Particle Instance modifier edits the mesh of an object,
rather than creating copies/instances of that object.

There are a lot of reports with the same "white screen" problem, use search.

The "first" element is not the first, it is the previous selection area,
before you perform Pick Shortest Path (or Shortest Path from menu),
so it should remain unchanged.

At first, check the geometry:

There's no bug.
You need a smoke material:
https://docs.blender.org/manual/en/dev/physics/smoke/material.html

Confirm, not only "Array" modifier, but also "Mirror" modifier.

Yeah, there is some blurring at the default values.
Assume that the image is recalculated (always) which leads to blurring.

I have a Russian/English keyboard.
There is a '/" key (single/double quotes).

Yep, you cannot select bones, because (in the Weight Paint mode) LMB is employed for painting.

You paint with LMB, and select bones with Ctrl-LMB.

This worked as "Toggle" until version 2.64,
there have been some changes: rB19e1d05461ab.
Just forgot to set "extend" to FALSE.

You select all elements but skip (not select) every Nth, (like 3, 6, 9...).
The Skip - number of consecutive elements to skip (not select) at once. (That breaks the "every Nth" logic.)

Default font and zoom size, hinted looks terrible:

You can disable "Text Hinting" in User Preferences > System.

@Bastien Montagne (mont29) If you save the file, it will not crash anymore. You need to reproduce exactly this steps.

@Chris Cook (CCook) Create a file until the last step, this file will save time.

Confirm, axis locking broken in 2.79.6 (work 2.79.4).
But Shift-LMB seems to be working with Maya preset.

2.79.6 Win7 32

The problem lies elsewhere.

I just read the tooltip as "move the flipping point and then flip over it",
but here it first flips and then moves, i.e. it's just a offset.

Some remarks:

OK, "Flip U/V Offset" should shift the flipping point from the 0.5 (as tooltips says).

When you open a 2.79b file in 2.79.6, the Roughness value is converted. rB7613ffc944eb
When you link a 2.79b file, the Roughness value remains unchanged.

Looks like there's a problem with the 32-bit float image.

Note, this is a huge file 43000 x 14000 px.

74.  "Surface falloff (New)" -> "Surface"
75.  "Every Point (New)" -> "Every Point"

A packed PSD file can't be load, although it exists and can be unpacked.

Just try to paint in the Vertex Paint mode, with Subtract blend modes.
It will erase alpha channel (similar to Erase Alpha), which is weird.

Just try to paint in the Vertex Paint mode, with Falloff Angle set to 30, and big brush radius.
Where the stroke overlaps itself takes place artifacts.

UV Editor > Select menu > Select Split

@Campbell Barton (campbellbarton) I also believe there is a problem with "Checker Select", in how it calculates the Offset.
