### Problem or use case

As someone with ADHD, I get distracted very easily and struggle to remember short-term details. When working with Orca, I usually switch between different projects and tabs.

I rename tabs to remind myself what they contain, but the current tab width is not enough. Often, only a small part of the names I write is visible.

Therefore, tab widths should be adjustable.

### Proposed solution

The tab width could be adjusted directly with the mouse, or a tab-width setting could be added to Settings.

### Alternatives or additional context
