-All tested on win 10 64bit Inkscape 0.92pre3 15195.-
Future releases will be improved.
(1) gradient mesh copy-paste adds unwanted transformation Edit
Gradient mesh is added to a rectangle,
then the rectangle is scaled by bounding box handles.
Object is copy/pasted, resulting the gradient mesh is in wrong scale on the pasted object.
Same thing with regular paths. Pasted object's mesh is smaller and translated.
(2) gradient mesh cloning and editing parent results in instant crash
When cloning an object with a gradient mesh,
editing the parent's mesh results in instant crashing.
(3) gradient bending
Bend lpe doesn't bend gradient mesh.
Inspired by this topic.
By second thought, if a mesh shaped path is bent nodes added here and there messing up the net topology so it seems it's beyond the capabilities of any mesh tool for a long time. If all other options were working fine...
(4) gradient mesh, adding new nodes doesn't work
Adding new nodes/loop sometimes refuses to work.
Hovering the cursor over the mesh segment the cursor changes to have a + sign, double clicking.
Itt adds nodes a few times but then refuses to add new nodes by double clicking, although the + sign still appear.
Found when you first select two of the segment's nodes you can double click and add nodes again but that wasn't necessary the first time.
(5) gradient mesh deselects after new node added
Once you double click and finally add new nodes, the whole mesh gets deselected by a sudden while the mesh tool is still active.
Even worse when you can't add new nodes by double clicking it still deselects the mesh.
To top that, sometimes when you double click on the object once it has a mesh already, it replaces it with a completely new one.
(6) gradient mesh straight segment to curved doesn't work
Mesh segments can be set to be straight from the default curved one any time, even after new nodes are added but selecting two neighboring nodes and clicking the make curved segment icon doesn't do anything.
On a side note the node tool can edit the mesh nodes and handles but its make segments linear/curved option doesn't work either.
(7) gradient mesh moving and crashing on fill and stroke tab icon click
When a mesh node is selected and slightly moved, and after you click the mesh tab on the fill and stroke panel right after, strange things can happen.
Sometimes it modifies slightly the current mesh, sometimes it results in immediate crashing.
(8) gradient mesh issue, immediate crashing upon dropdown menu select
Steps to reproduce:
add a mesh to an object, edit the mesh nodes
select another object, and in the mesh tab of the fill and stroke panel choose the existing mesh from the dropdown list -instant crash.
(9) gradient mesh instant crash and not consistent behave with 3D boxes
Draw a 3D box, add a gradient mesh fill to it.
Nothing is rendered from the mesh.
Change one mesh node to another colour -still no action.
Let's move one mesh node -instant crash.
-To be fair it happened once but worked the other.
(10) mesh gradient issue with dropper tool
When multiple mesh nodes are selected, the dropper tool only changes the first selected one's colour.
