Are you frequently switching between UI packs for your wireframing ? If yes, then this is the feature that you are looking for. The latest release of WireframePro enables users to create meta UI packs that can merge multiple components packs into a single bundle. This not only reduces the effort to switch between packs but also helps in finding components across multiple packs easier.
Let us take for an example: You can merge two UI packs 'Handdrawn components' and 'Handdrawn icons' into a single pack for creating your sketchy mockups. Meta UI packs can be also customised to include any number of UI packs and the list can be also easily re-ordered to suit your needs.
