In small batch and individual production, the information about the operations on the details and their order is placed directly on the patterns. Sometimes, such info is quite not obvious. Now it is necessary to write this info on the detail patterns by hand. When the pattern parameters change (in the worst case -- every order), this work must be repeated on and on. This seems to contradict with the principles of Valentina project. The requirements for such info are different and depend on the developer guidelines. Some want to label selected lines and curves (Issue #769), others want to mark points to reference them from the text manual.
Adding text label tool would satisfy most of the use cases. The user should first select a point. Options should include: Detail selection combo box Edit box for the label text Angle and size of the text x-y displacement, relative to anchor point if manual dragging of the label is impossible. The ability to manually move the text around the anchor point would be ideal, but even the numeric parameters would suffice.
