January 2026 monthly work summary focusing on feature enhancements for code folding in JetBrains tooling across F# and Unity ShaderLab, with parity improvements and integration enhancements. Delivered two core features aligning with product goals to improve editor UX and cross-repo consistency.

Concise monthly summary for 2025-12 focused on delivering a feature and fixing a critical ordering bug in the F# plugin, with clear business value and technical impact. Overall, this month centered on improving code navigation and developer productivity in the JetBrains/resharper-fsharp plugin by ensuring that code folding options are ordered predictably and language-precedence-aware.

In August 2025, delivered a robust Code Folding State Persistence feature for JetBrains/intellij-community, enabling persistent folding state across sessions by caching the folding model on disk and introducing frontend/region management. This work included new mechanisms to track whether folding regions were created by the frontend and whether they should be collapsed by default, significantly improving code navigation and editing in large files. A critical bug fix addressed IJPL-189483: the "+Collapsed by default" setting was not changeable when disk caching for the folding model was enabled, now ensuring user preferences are respected. The changes enhance editor reliability, reduce confusion when reopening projects, and streamline navigation in complex codebases.
