These TODO-style comments should either be addressed or removed before merging. They indicate unfinished work regarding shortcut support in multi-select mode and suggest that the implementation is incomplete.

Suggested change

// Keep tabs but maybe hide shortcuts for multiselect if not supported?

// Assuming shortcuts are not supported in multi-select for now or handled same way?

// Existing logic launches helper activity for shortcuts. This breaks multi-select flow unless handled.

// For now, let's just make Multi-Select work for Apps which is the performance killer.

// In multi-select mode, selection is applied to applications/activities only;

// shortcuts continue to be created and handled individually via the shortcut flow.

The filter method calls lowercase() multiple times per search query, which can be inefficient for large lists. Consider caching the lowercase versions of entry names and display names during initialization, or use a more efficient search algorithm to improve performance when filtering hundreds of apps.

+            txt.text = item.displayName

+            if ((context as IntentSelector).allowMultiSelect && intentType == IntentApplicationEntry.IntentType.Main) {


The checkbox visibility logic only shows checkboxes for IntentType.Main, but launcher activities use IntentType.Launcher. This means the multi-select checkboxes won't appear for launcher activities (the most common app type). The condition should check for both IntentType.Main and IntentType.Launcher to ensure users can multi-select regular apps.

Suggested change

if ((context as IntentSelector).allowMultiSelect && intentType == IntentApplicationEntry.IntentType.Main) {

if ((context as IntentSelector).allowMultiSelect &&

(intentType == IntentApplicationEntry.IntentType.Main ||

intentType == IntentApplicationEntry.IntentType.Launcher)) {
