Hi everyone,
In my opinion it would be VERY handy to be able to quickly rename any entity in the tree in all tabs (Geometry, FE Model and Results) by pressing F2 while the entity is selected, as in most Windows programs.
A nice extra could be a multiple rename when multiple entities are selected: you display a modal windows that asks for the “root name” or something similar, and PrePoMax renames adding “_1”, “_2” progressively to all selected names.
Best regards
