it's so good to know that there are many of us out there. I eventually unistalled LR it really was driving me crazy but I hear so many good things about it that i'm tempted to reinstall it. I do have the time but wow it seems so complicated especially the exporting a file to a jpeg or along those lines. I also have NX-D which apparently is great but also find the import export part a little compllicated. For quick editing I use Fastone, views all files and has quick editing function with resizing and a save as function perfect for posting to FB etc
With NX-D there is no "Import". Just point the file manager of NX-D to the directory holding images (RAW or jpeg or TIFF), and they are displayed in the program. NX-D does create a "side car file in a subdirectory where the files are. So it is better to keep the files date wise or subject wise to reduce the number of files loaded into NX-D at start up.
Export is quite easy. Just select the files from the thumbnails displayed, right click, select convert, choose jpeg in the dialog. Choose the output size, and tailor the file naming to your satisfaction. I use the original file name. The settings are remembered, so you have to do it once only. Then start the process. NX-D will generate the jpeg files and put them in the directory you selected.
You can also "Batch Edit" all the files. Just select all the files you want, then select the adjustments and they will be done to all the selected files.
Here is my workflow
