Batch operation indication

[realbsb]

Description of the new feature or improvement

Batch commands using CTRL+G work on selected files, we know their number before running the command. As a rule, the execution of one iteration lasts at least a second and already takes a significant amount of time on 30 files. Usually by then the user's attention has switched. Wouldn't it be better to display progress indication in the header?

Proposed technical implementation details (optional)
