    Windows Forms is a .NET UI framework for building Windows desktop applications.

    Project mention: Ask HN: Any way to write a simple desktop app anymore? | news.ycombinator.com | 2024-01-22

    Windows Forms[0] is still alive and will never die, and very low overhead to start with, and works on new and shiny .NET 8.

    If Linux or macOS, you can use AvaloniaUI[1] instead which is sufficiently advanced but assumes some prior knowledge.

  • Depressurizer

    A Steam library categorizing tool.

    Project mention: I wrote an app for myself to filter my library by HLTB | /r/SteamDeck | 2023-12-11

    Another thing you can do is use a Steam tag management system like Depressurizer to automatically tag games with their approximate HLTB time (eg. 1-5 hours could be a category, 6-10 hours could be another category), then on Steam Deck you can use the Tab Master plugin for Decky to show each HLTB categories as a separate tab. There are probably other ways to display the categories as well.
