Restore the ability to resize the crop rectangle by dragging on any point on the crop boundary.
Restore the ability to set the crop outline's top, bottom, left and right values in the Tool Options palette. Plus add a numeric control for angle.
Allow the crop boundary to extend outside the image while rotating.
Restore the ability of the Resize dialogue to remember the last used settings.
Restore the ability to set control points in the Curves dialogue by clicking on a point in the image. Also restore numeric controls for the control points.
Restore the ability of PSP to open multiple instances.
Update all the tools and filters so that they work on 16 bit/channel images. This especially includes the plugin interface.
Allow plugins to see EXIF data.
Raw processing currently gives extremely poor results. It needs a complete overhaul that includes pre-processing, especially for colour temperature and exposure, and it needs to change demosaicing from the antiquated VNG method. Needs to record the settings from the raw pre-processor in a small "sidecar" file.
A "Vibrance" filter to selectively increase saturation.
Lab mode editing.
Full access to channels.
The Organizer needs to work much, much faster, be much more stable and to quickly and accurately reflect changes. Needs to have the ability to exclude video file types from cataloguing. Desperately needs tools to maintain, clean, repair and backup the database.
A simple file browser, either separately, or as part of the Organizer.
The Depth of Field filter is currently just a toy that creates a blurred vignette rather than emulates shallow depth of field. It needs to be able to use selections from the real selection tools, and depth mapping.
A Vignette tool that can both darken the corners, and correct darkening in the corners of an image.
Improved working with gradients. More control of direction and placement by applying them by drawing them on an image. Enveloping of a gradient to a selection.
Add and edit text directly on the image rather than using a text entry box.
Ability to disable sharpening in Smart Photo Fix.
Extend the Graphite theme to the rest of the program and fix the redraw problems.
Make the darkness of the Graphite theme customizable.
Overhaul the program icons. Some are too similar. Some are hard to make out.
Either restore the Pick Tool to separate tools for vectors and raster, or make it so that it can be locked in one mode. Currently, you can select it to be in vector mode on the Tool Options palette, but as soon as you try and use it, for instance to marquee select a group of vector objects, it reverts to automatic mode, latches onto the raster layer beneath the vectors, and you drag the raster layer instead.
Having two Protexis licensing services running, and installing them without fully informing the users, causes much fear, uncertainty and doubt. Corel needs to be completely up front and honest about the whole process, so that their users know that it isn't spyware and that it isn't impacting on performance.
Addition of a command for matching the colours of one image to another. (Similar to the Match Color command in Photoshop).
A panorama tool... and a really good high quality one.
Fix the vector drawing engine that was broken in PSP8, so that it works correctly with lines that have a width that is an odd number of pixels.
EXIF - better support, better preservation of all fields, tools to edit it and back it up. Support for EXIF in compressed TIFs.
More resampling methods... Lanczos, sinc, spline, adaptive of some sort.
More blurring methods, particularly a bokeh based method.
More sharpening options and the ability to leave high pass sharpening as separate layers.
More layer blending options.
More layer styles and numeric controls to make all layer style effects accurate, reproducible and capable of being described in a tutorial.
It basically boils down to a few decisions -
Does Corel want to present a serious tool for photographers? It currently markets PSP as a professional tool, but at the same time removes the precision from many tools, fails to keep up with current trends, has ceased to be innovative, and has too many amateurish toys that are promoted as major features.
The second main decision is what Corel wants to provide for the painters, digital content creators, scrapbookers and so on, who were once the majority of PSP users. Almost nothing has been done for them in recent years, and a great many of the user groups and web resources are no longer there, or haven't been updated for years, or have changed their focus to Adobe. An enormous amount of goodwill has been frittered away.
