Well, I'm not sure if the code is the most elegant, but I did the best I could. The changes are ready for review. @Kryptos-FR

[Kryptos-FR]

Don't really agree with the changes. I will need more explanations for them.

[Jklawreszuk]

To be honest, I had no vision with light theme, so It made me think, "Hey, since the buttons are transparent now, we can consider this both a light and a dark theme isn't it?" Also It was something off with the previous light theme, but I guess It was simply background which was too much dark indeed. So I will try to think liltle bit longer about light theme.

[Kryptos-FR]

I'm replacing some of the images with vector images. This should work better with dark/light theme.

[Kryptos-FR]

I think I came up with a good compromise for the light theme. It's definitely better than before. There are still a few icons to replace with vertex geometry.

Dark:

Light:

I am not sure what to think about the button background change, but we can always reiterate by making another PR 😅. Overall I would say its 100% better with these new vector icons. The only this is missing icons for "Projects" and "Switch/update version". Other than that, I have no comments.

@Kryptos-FR I think we'll want a new launcher release soon with all the changes (.NET 11, hiding 4th digit in version numbers for 4.4+, and I think there were a few other important bits to support 4.4 well)

Should we merge this in before final testing?

Maybe need to fix #3438 as well?
CrashReporter better stay in-process, right? (it's not like we load native libraries so it should be only .NET unhandled exception, easy to handle)

[Kryptos-FR]

@xen2 I have 4 more images to replace with vector graphics. I already added a fix for #3438 in this branch (with a MaxWidth). For wrapping I need to check the behavior in MarkView.Avalonia since we use a markdown viewer for the content.

We can keep the crash reporter in process for now. I'll need more time to find a proper solution (if any is needed).

Should we retarget this PR to master-4.4?

[VaclavElias]

Light theme looks also nice.

[Kryptos-FR]

Remaining icons converted. @xen2 ready to be tested and merged if no issues.

edit: I tried to pack the Launcher and add it to the local NugetDev. The old launcher picked up the update and then nothing. I'm not sure the current publish profile is working as expected.

edit2: my bad. I did not run -t:BuildLauncher before -t:PackageLauncher so my initial build wasn't single file.

We can keep the crash reporter in process for now. I'll need more time to find a proper solution (if any is needed).

Yes, I think it works fine for our purpose as it is (pending final testing on real package).
No need to make it much more complex for cases we don't need (native crash, etc.).

I'd rather keep time/energy to focus on the launcher itself, Avalonia port, 4.4 release, 4.5, etc.

[ferafiks]

Light mode is less readable than dark. It could be improved if the background image had boosted dark levels and a blur, similarly to the dark version. Here's a rough version of that, I don't have much time right now to build and test it:

[Kryptos-FR]

@ferafiks I have actually "lighten" the original image.
