Use bold text to "highlight" matching parts within task titles in global search results
The global search matches both titles and contents in notes, and there is the "Matches" column to tell you where it was found, but I would still like having a clearer visual indication that lets me see at a quick glance "which of the search results are matching on titles and where".
Instead of using a highlight color (which might mess up depending on the theme etc.), my suggestion would be to use set bold type on the parts of the title strings that match, while the searchbar / search results are active.
For performance optimization reasons and/or to avoid too much UI jitter, maybe the bold text property could be applied with a small timeout delay (ex: 250ms) instead of immediately on every keystroke.
This was tested in version 41.3 in Fedora 35.
