    I inspect them visually and this gives me more info about the widgets. I can quickly understand or learn the application if the IDs are informative and consistent.

    I assume tools such Illuminations for Firebug could parse the ID and generate even more useful info.

    Easy way to visualize components... if you open firebug (or the like) and mouse over DOM elements, it will highlight it. No change required for that.

    I use Illuminations. This works great, but only in Firefox.

    Take a look at Ext css class names - they are consistent and informative.

    The effort to correct the generated ID names is miniscule, but better names would provide helpful information.

    I don't really see this as being much of an issue, though I guess it might be something we could look at eventually.

    However I wouldn't say the amount of effort is miniscule, there's many more important things to look at now.

    Default [REOPEN] Ext auto-gen ID format

    Ext.Component's getId() changes between releases:

    Code:
    // Rel 3: As you can see the ID is not very informative.
    // It's just a prefix + sequential number.
    getId : function(){
    	return this.id || (this.id = 'ext-comp-' + (++Ext.Component.AUTO_ID));
    }
    
    // Rel 4: This is better b/c the ID includes the xtype prefix.
    getId: function() {
    	return this.id || (this.id = (this.getXType() || 'ext-comp') + '-' + this.getAutoId());
    }
    
    // My suggestion:
    // Modify this method to have the "ext" or "x" prefix,
    //   so it sorts nicely in the Ext widget registry.
    // This is a small change that provides further improvement to the ID format.
    getId: function() {
    	return this.id || (this.id = 'ext-' + (this.getXType() || 'comp') + '-' + this.getAutoId());
    }
