I think installed here looks a bit weird @sumitst05. Probably on my KDE machine only.

I feel like this should be more pronounced.. this is nothing but a mere styling nuance.

Another small quirk on the search tab. Can be made more coherent. I think it just looks a little out of place

I'll test this week and add my review. Thanks for being so patient @sumitst05

I have made the following changes:

• Deduplicate conflicting rules (package-card, status-badge, repo-badge, view-title, log-viewer were each defined twice with different values)
• Consolidate the mixed gray/zinc palettes into one documented scale in base.qss
• Style previously-default surfaces: QMenu dropdowns, checkbox/radio indicators (new SVG check + combo chevron in resource/icons), message boxes, horizontal scrollbars, generic QProgressBar
• Add primary-btn (Search, Update All, Install) and danger-btn (Uninstall) button roles with the ALG blue accent
• Align Home/Search titles to the shared view-title style instead of programmatic fonts; drop leftover no-op font code in updates_widget
• Set WA_StyledBackground on UpdateItem so its card styling actually paints
• Fix stale 0.2.28 version string in the About dialog (branch ships 0.2.30)

I still believe that the "installed" can be made a bit better, but I am open to keep it as it, as long as you feel it is fine. I am still testing on KDE, so please review this in your respective environments and let me know.

Sorry for the fact that I took a while to review this.

Hey @demonkillerr, I fixed a few issues and made some minor changes.

I found 2 issues that can be addressed later on. Here are those two issues: #26 and #25. I haven't found any other issues in Plasma, XFCE, or GNOME yet.

Soooooo, I have approved the PR.

looks good just now
