"Enable gradient editing" in preferences allows stop deletion, but not addition
Migrated from https://bugs.launchpad.net/inkscape/+bug/1579395, opened by @Moini #### Steps to reproduce: <!-- Describe what you did (step-by-step) so we can reproduce: --> - open Inkscape - create a gradient and add another stop in the center by Ctrl+Alt+Click with the gradient tool - Make sure the Node tool has "Enable Gradient editing" set to true - Enter the node tool - Delete the center stop using Ctrl+Alt+Click - Add a new stop using Ctrl+Alt+Click #### What happened? Nothing. #### What should have happened? A new stop should be added. If deleting works, adding should work as well. (Same for adding by double-clicking, which works in the Gradient tool) #### Inkscape Version and Operating System: * Inkscape Version: 1.1-dev (c990a67, 2020-04-09) * Operating System: Windows 10 * Operating System version: 10.0.18362 #### Migration info In the LP issue, there is a long discussion whether this is a regression or not. tl;dr: it's probably not. > I just noticed there might be interference with 'Select under disregarding groups' for the Alt+Ctrl+Click thing - at least when 'enable gradient editing' would be checked for use with the selection tool (no problem for node tool) > On-canvas actions which were/are limited to the gradient tool (new in 0.42): > - adding a new gradient, > - nudging selected gradient stop with arrow keys, > - using <TAB> to move selection from one handle to adjacent one, > - deselecting selected gradient stop with <esc>, > as well as features added later to the gradient tool: > - reversing gradient direction (Shift+R) (0.44), > - selecting multiple gradient stops, with keyboard (0.46), > - selecting multiple gradient stops, by dragging a selection frame (0.46), > - adding intermediate stops (0.46), > - simplifying selected stops with Ctrl+L (0.46), > - ...
