Thank you Walt - I had accidentally dragged the layers above one another and assumed that this would work equally. Now I used "arrange layers" and It worked a treat! Thank you very much ❤️
What DM1 said, and see the Help under the Node tool for all of those icons (leftmost 5 are snapping, rightmost 4 are about transform. Note: you're missing a couple of transform icons that may not show up in portrait view).
Accessing the help on an iPad: go back to the gallery and tap on the question mark in the top right corner. Type node into the search box i the top left corner, and tap on Node Tool, scroll down to see the icons and their explanations.
Not sure if this will paste properly (note: if you hold Ctrl, or Cmd on a Mac, and rotate your mouse wheel, you can zoom your browser for a better view):
Action—Manipulates the curve(s):
Break Curve opens the shape at the selected node.
Close Curve joins the start and end nodes to create an enclosed shape.
Smooth Curve modifies a line or shape, by adding and removing nodes, to make it more aesthetic.
Join Curves connects two separate curves together to make one curve. Curves need to be both selected with the using either the Node Tool or as you draw.
Reverse Curve lets you draw from the opposite end of the curve—The start node becomes active, ready for further drawing.
Transform—Transforms the selected node(s):
Transform Mode—when selected, creates a bounding box around the selected nodes, allowing them to be transformed as a grouping.
Enable Transform Origin—displays a movable transform origin about which the selection box can be rotated.
Hide Selection while Dragging—when selected, the selection box is temporarily hidden when transforming. If this option is off, the selection box remains visible during transformation. The selected behavior persists across all objects unless it is manually switched.
Show Alignment Handles—when selected, displays alignment handles at the center and edges of the selected object. Hovering over these handles displays a floating guideline across the page. You can drag the handles to position the center or edges of the selected object in line with this guide.
Transform Objects Separately—when selected, where multiple objects are selected, they can be be resized, rotated and sheared independently of each other instead of transforming the bounding box.
Selection Box From Curves—when selected, the selection box encompasses and includes all curves that extend outside the array of currently selected nodes.
Cycle Selection Box—after reshaping, rotating, or shearing the shape, this option resets the selection box to vertical.
Snap—Controls node snapping:
Align to nodes of selected curves—aligns any moving node you drag to any other node on the same or a different curve.
Snap to geometry of selected curves—will snap moving node to the same or different curve's path or node.
Snap all selected nodes when dragging—will snap multiple selected nodes, when dragging, to a "target" node on any selected curves.
Align handle positions using snapping options—will snap a control handle to a curve's path (or node) or shape's geometry. With global snapping's Snap to Grid enabled, you can also snap control handles to grid.
Perform construction snapping—allows control handle snapping:
inline with adjacent node.
to 90° from inline.
to reflected angle with adjacent control handle.
parallel to adjacent control handle.
90° to parallel control handle.
to logical triangle.
These options are independent of the global snapping options.
In all seriousness, though. Can you open a Kickstarter for a Linux version, and actually see how many people would back it up? Cover the prices that it would take to make it, and we'll see how many people would back it up. If you don't want to go through the trouble of posting something, what's the legality for one of us to open it up, and only if it passes your threshold, only then we'd receive the money and pass it onto you?
