VinciFlow - Stream Graphics Controller 3.4.4

Bug Fixes​

• Subtitle Color Inheritance - Fixed an issue where subtitles in the default lower-third template were incorrectly inheriting the title color.
• Import Override - Resolved a bug where importing configurations could unintentionally overwrite existing titles and subtitles.

User Experience​

• Contextual Tooltips - Added helpful tooltips across various features to improve clarity and user guidance.
• UI Polish - Corrected multiple typos throughout the application for a cleaner, more professional interface.

Groups & Layout​

• Sort by Group - Added a new Sort by Group button to the left-side navigation row in the Groups Dialog.
• Tabbed Editor Redesign - Reworked the right-side editor into a tabbed interface, clearly indicating that Carousel behavior is a group-level feature.

System Architecture​

• Per-Scene-Collection State - Rewrote the state management system to support independent states per OBS Scene Collection. The selected Browser Source is now persistent and correctly restored when switching between collections.

Styling & CSS​

• Position Element (Advanced Styling) - Introduced a new Position Element option in the positions dropdown, allowing direct styling of the parent list item. This is especially useful for scoreboards, ensuring animations remain smooth and flicker-free.
• Advanced CSS Scoping - Implemented robust CSS binding to scope all styles to their respective parent IDs, preventing cross-template style bleeding.

Fixed the update checker
Added an extensive check on API parameters like param_x_Y now you can use long type string to replace the values easier

Each lower third can now define an API Template in the Layout settings.

- A JSON object describing runtime fields (e.g.

Code:

score

,

Code:

player

,

Code:

team

, etc.).
- Stored in the project configuration and exported/imported with templates.
- Validated in real time in the UI (syntax and object shape).
- Acts as a schema and default seed for generated parameter files.

I am moving forward as VinciFlow. This rebrand eliminates any confusion with similar plugins and solidifies the position as the premier choice for dynamic broadcast automation and sports interfaces

Smart Lower Thirds – Development Update

This update focuses on Groups (formerly Carousels), scheduling accuracy, hotkeys, dock UI polish, and startup refresh behavior.

Spoiler: Groups (formerly Carousels)

- Carousel concept was refactored into Groups.
- Groups now fully control their own playback, timing, and visibility.
- Backward compatibility with existing setups is preserved.

Spoiler: Exclusive Mode per Group

- Added Exclusive option to Groups.
- When enabled, showing one lower third in the Group hides all others from that same Group.
- Works for manual triggers, hotkeys, and automation.

Spoiler: Accurate Group Timing

- Group Visible Duration and Time Between Items now work correctly.
- Values are set in seconds in the UI.
- Active lower third shows a live “Hides in mm:ss” countdown while the Group is running.

Spoiler: Manual Override Behavior

- Manually triggering a lower third from the dock now stops its running Group.
- Prevents scheduler conflicts.

Spoiler: Group Hotkey (Toggle)

- Each Group now has a single Toggle Hotkey.
- Press once to start, press again to stop.
- Same selector UI as individual lower thirds.

Spoiler: Hotkey Conflict Protection

- Hotkeys are now globally unique.
- Assigning a hotkey that is already used clears the previous assignment automatically.
- All hotkeys are saved and restored on OBS restart.

Spoiler: Dock UI Improvements

- Resources, Browser Source, and Browser Size rows now use a clean two-column layout.
- Group checkboxes (Loop, Exclusive) are aligned on the same row under Dock Highlight Color.

Spoiler: Startup Refresh (Version & Marketplace)

- Plugin now checks for new versions and marketplace updates on every OBS launch.
- Local cache is only used when offline.

This update brings more reliable automation, precise group scheduling, conflict-free hotkeys, a cleaner dock layout, and always-fresh marketplace data.

Now all placeholders can be used across all template files allowing you to customize the lower thirds even further

The github issues were fixed and now the update is live

Due to a massive outage on launchpad.net the github compilers could not build the artifacts so the last version is not yet available

We’ve implemented four new color placeholders to give you even more control over your lower thirds. By adding {{TITLE_COLOR}}, {{SUBTITLE_COLOR}}, {{PRIMARY_COLOR}}, and {{SECONDARY_COLOR}} along with new smart fallback logic, template developers can now offer end-users deeper levels of customization than ever before.

✨ Summary
