This PR addresses Issue #8334 by enabling users to schedule model switches while Roo is actively processing a request.

Summary

Currently, the model selector dropdown is completely disabled during execution, preventing users from changing models until the current request completes. This PR implements a scheduling mechanism that allows users to queue a model switch that will automatically apply after the current request finishes.

Changes

Core Implementation

  • Modified ApiConfigSelector component to remain interactive even when disabled
  • Added scheduling state management with scheduledConfigId and onScheduleChange props
  • Implemented automatic application of scheduled switches when requests complete
  • Added visual indicators including clock icons and border highlights for scheduled models

User Experience

  • Users can click the model dropdown during execution to schedule a switch
  • Scheduled switches are visually indicated with a clock icon
  • Users can cancel a scheduled switch by clicking the same model again
  • The scheduled model is highlighted with a border in the dropdown

Testing & Quality

  • Added comprehensive unit tests for all new functionality
  • All existing tests continue to pass
  • Added translation keys for internationalization support
  • Code follows existing patterns and conventions

Testing Instructions

  1. Start a long-running request with Roo
  2. While the request is processing, click the model dropdown
  3. Select a different model - you should see a clock icon appear
  4. Wait for the request to complete
  5. The model should automatically switch to your scheduled selection

Screenshots

The implementation adds subtle visual indicators without disrupting the existing UI:

  • Clock icon appears next to the current model when a switch is scheduled
  • Scheduled model is highlighted with a border in the dropdown
  • Tooltip text updates to indicate scheduling behavior

Fixes #8334


Important

Introduces model switch scheduling during execution with UI indicators and state management in ApiConfigSelector.tsx, tested in ApiConfigSelector.spec.tsx.

  • Behavior:
    • Allows scheduling model switches during execution in ApiConfigSelector.tsx.
    • Adds scheduledConfigId and onScheduleChange props for state management.
    • Automatically applies scheduled switches post-request.
    • UI updates include clock icons and border highlights for scheduled models.
  • User Experience:
    • Users can schedule a model switch by clicking the dropdown during execution.
    • Scheduled models are indicated with a clock icon and border highlight.
    • Users can cancel a scheduled switch by reselecting the same model.
  • Testing & Quality:
    • Adds unit tests in ApiConfigSelector.spec.tsx for new scheduling functionality.
    • Updates translation keys in chat.json and prompts.json for internationalization.
    • Ensures all existing tests pass.

P0: This appears to add a git submodule (mode 160000). This is likely unintended and will introduce a submodule pointer into the repo. Please remove this entry from the PR (drop the submodule file or reset the tree to exclude it).

P0: Another unintended git submodule pointer. This will create a submodule under tmp/. Please remove this from the PR to avoid repo pollution and CI/tooling issues.

P1: When disabled is true but onScheduleChange is undefined, selections will still call onChange(configId), applying the switch immediately during execution. That breaks the scheduling-only behavior. Consider guarding this path.

Suggested change
onChange(configId)
} else {
// Apply immediately when not disabled; but if disabled without scheduler, ignore
if (disabled) {
return
}
onChange(configId)
}

P2: Accessibility. The trigger is intentionally kept enabled (disabled={false}) to allow scheduling while execution is in progress, but it lacks aria-disabled. Adding aria-disabled preserves semantics for assistive tech while retaining interactivity.

Suggested change
disabled={false} // Always allow opening the dropdown
disabled={false} aria-disabled={disabled} // Always allow opening the dropdown

(configId: string) => {

P2: UX edge case. If a user selects the current model while disabled (no schedule yet), we end up “scheduling” the same model. Prefer treating this as a no-op (or cancel any existing schedule). This improves clarity and avoids a clock icon that implies a change that won’t happen.

Suggested change
if (disabled && onScheduleChange) {
if (disabled && onScheduleChange) {
// When disabled, schedule the change instead of applying immediately
if (configId === value) {
// Prevent scheduling the current model
onScheduleChange(undefined)
setOpen(false)
setSearchValue("")
return
}
if (scheduledConfigId === configId) {
// If clicking the same config, cancel the scheduled change
onScheduleChange(undefined)
} else {
// Schedule the new config
onScheduleChange(configId)
}

P3: Recommend adding a test for the case where disabled === true and onScheduleChange is not provided to ensure no immediate onChange occurs (selection should be ignored or require scheduler).
