Drop 1:2.5: on a grid of 10 it steps by 4, which misses 10, so texts on two elements 10 apart could never line up. Every remaining divisor is a whole number, which tst_textgrid checks. The divisor list and the snapping arithmetic move to the header-only textgrid.h so the toolbar menu, the preferences page and the test share them. The preferences page gets the same choice under Grille + Clavier; QETApp::textGridChanged keeps every editor's toolbar button in step. While element texts are dragged, the status bar names the text grid and says to release Shift and hold Ctrl for free placement -- Ctrl+Shift together is the pan shortcut.
