Best way to delete a bar

Looking for suggestions on the best way to delete a bar so that all the tempo changes move as well.

There is no “easy” way to delete bars (or to add them, which is as important).
The only way is to manually select all notes, choose “select parameters with notes”, drag them and correct tempo changes manually.
Tedious, and prone to error, IMHO.

A script could perhaps be made to automate it, and Dreamtonics should add the function.
