Ilia Zakoulov
Over a three-month period, contributed to JetBrains/intellij-community by overhauling and integrating the non-modal Welcome Screen, focusing on modular design and improved onboarding for PyCharm users. Leveraging Kotlin and Java, implemented dynamic content providers, XML-defined actions, and automatic Python source root detection to streamline project setup and enhance user experience. Addressed UI stability by ensuring updates ran on the Event Dispatch Thread and improved compatibility with JVM 21. Refactored legacy components, consolidated dependencies, and introduced telemetry for onboarding features. This work reduced configuration overhead, improved maintainability, and delivered a more reliable, discoverable Welcome Screen across multiple IDE contexts.

Sep 1, 2025Month: 2025-09 Concise monthly summary: In September 2025, contributed to onboarding and welcome-screen improvements in JetBrains/intellij-community, delivering user-facing features for PyCharm and stabilizing the Welcome Screen UX across JVM 21 while laying groundwork for future onboarding experiments. Key outcomes include: Key features delivered: - PY-82074: Non-modal Welcome Screen for PyCharm with PyMiscService, Learn IDE displayed in the editor tab, automatic left-pane enablement when the welcome screen file is selected, new actions under New..., custom icon, and plugin icon tint for non-modal Welcome Screen; added non-modal welcome screen entry to plugin-content.yaml. - IJPL-202286: Welcome Screen Core Improvements – Introduced WelcomeRightTabContentProvider, internalized classes, simplified non-modal welcome screen EP names, bundle pointer usage, OpenWelcomeScreenAction, improved focusing behavior, and API dump; removal of non-modal welcome screen from community modules. - IJPL-202286: Welcome Screen overhaul/refactor – Bundle regeneration, removal of obsolete providers/icons, JVM 21 compatibility, UI/behavior enhancements, experimental flag, and related cleanup (tips, API, dependencies, wording). Major bugs fixed: - PY-82074: Fix focusing of Learn IDE tab. - Fix miscellaneous button on the old welcome screen. - JVM 21 compile-related fixes and theme/background image handling improvements for Welcome Screen. - Do not launch WelcomeScreenProjectActivity in headless/CLI test environments. Overall impact and accomplishments: - Improved onboarding experience for PyCharm users with a non-modal, more discoverable Welcome Screen and related New... actions. - Increased stability and performance through UI/UX refinements, JVM 21 compatibility, and API bundle improvements. - Reduced maintenance burden via consolidation, internalization, and cleaner dependencies. Technologies/skills demonstrated: - IntelliJ Platform SDK (Kotlin/Java), JVM 21 compatibility, UI/UX design, internationalization/internalization, bundle management, API cleanup, and testability in headless/CLI contexts.
