In recent releases QGIS’ map composer has undergone some large usability improvements, such as the ability to select and interact with multiple items, and much improved navigation of compositions. Another massive usability improvement which is included in QGIS 2.6 is the new “Items” panel in the map composer. The panel shows a list of all items currently in the composition, and allows you to individually select, show or hide items, toggle their lock status, and rearrange them via drag and drop. You can also double click the item’s description to modify its ID, which makes managing items in the composition much easier.
This change has been on my wish list for a long time. The best bit is that implementing the panel has allowed me to fix some of the composer’s other biggest usability issues. For instance, now locked items are no longer selectable in the main composer view. If you’ve ever tried to create fancy compositions with items which are stacked on top of other items, you’ll know that trying to interact with the lower items has been almost impossible in previous QGIS versions. Now, if you lock the higher stacked items you’ll be able to fully interact with all underlying items without the higher items getting in the way. Alternatively you could just temporarily hide them while you work with the lower items.
This feature brings us one more step closer to making QGIS’ map composer a powerful DTP tool in itself. If you’d like to help support further improvements like this in QGIS, please consider sponsoring my development work, or you can contact me directly for a quote on specific development.
