[Feature] User-assisted placement #156
Description
Description
Add a feature in the UI that allows users to edit the current placement of pieces in the nesting arrangement and add the modified layout into the population.
Motivation
Some layouts have suboptimal arrangements that are obvious. Being able to quickly make small adjustments (like nudging pieces into better positions) may help steer the algorithm or guide it to a new placement.
Proposal
A button in the UI when clicked opens a similar window. There the user can select pieces and move them up and down, and rotate them. After all is done, the user confirms the changes, and the modified arrangement would be checked not to have issues (overlapping), and if all is OK an "Add" button will be enabled where when clicked the configuration will be added to the result of the current round's population for evaluation.
