Description

Describe the bug

I run some commnds using global shortcuts that do not require copy q window to show up. However, while they are simple, they sometimes take several seconds to paste transformed text.

To Reproduce

The two commands used in the screen recording:

paste source.ini.txt deepl.ini.txt

Expected behavior

Feel instantaneous regarding the simplicity of the commands

Research direction
Investigate the command execution pipeline to identify performance bottlenecks. Focus on how global shortcuts trigger commands and the clipboard content processing. Use profiling tools to measure execution time. Look at files in src/app/ and src/plugins/ related to command handling.
