Just posted to Adobe's feature requests;
http://feedback.photoshop.com/photoshop_family/topics/lightroom_5_feature_requestsAll would useful and productive to me, YMMV, but I think it is all achievable and the expectations are realistic. Hopefully someone at Adobe will listen.
General
A global history option;
A list of what files have recently been written to (edited/exported) and in which module.
Library;
This module is almost perfect but there are two areas where significant improvements can be made;
Keywording:-
1. Significantly increasing the number of the keyword suggestion options (buttons).
2. Increasing the number of keywords allowable in a set and increasing the number of buttons to accommodate this.
3. Having the option of a third keywording panel. This would allow suggestions/recent/sets to all be easily accessible.
Library filter:-
Allowing multiple search criteria within the catalogue (in the same style as creating a smart collection).
eg must contain keyword “England” AND keyword “garden”, but NOT contain “lawn”
Develop module
Local adjustments:-
Adjustment Brush;
Move “show selected mask overlay” option to mask control drop down box. (like ACR)
Add buttons to change overlay colour (maybe two pre-configured options). (like ACR)
Add HSL range of options.
Gradient Mask;
Add overlay provision as above.
Add HSL options.
It would also be nice to partially erase areas of the mask using the adjustment brush.
History
Add an indication of where in the history a “before” state is being shown from. (Emboldening the text of the state or an added asterisk would help this)
Book module
This absolutely needs the ability to work without templates, custom layout and custom sizes.
The ability to place text boxes freely anywhere on the page.
Print
The ability to place text boxes freely anywhere on the page.
