Icon changes in settings

[Taitava]

As is shortly discussed here, I'm planning to change some of the current icons.

I want to bring up my ideas here in this discussion before I'll actually implement them. Please comment here if you would like to change any of the icons. All available icons can be seen listed here: https://lucide.dev/

Tabs

Tab	Current icon	New icon (proposal)
Shell commands		*
General		*
Environments (from 0.12.0 onwards) / Operating systems & shells (prior to 0.12.0)		laptop
Preactions		sunrise **
Output		sunset **
Events		wand or keep unchanged
Variables		*

Other functions

Function	Current icon	New icon (proposal)
Execute now		*
Delete shell command		*

Informational icons

Information	Current icon	New icon (proposal)
Asks confirmation before execution		user-check
Ignored errors		eye-off

---

*) These icons will probably stay the same, unless further ideas come up.

**) Uncertain, would like to change to something better.

New icon sizes show up bigger than old icons here in this discussion, but the size of the new icons may change during the actual implementation.
