I haven't upgraded to 9.1 because of the new bugs introduced with that upgrade.
Well, 9.0.1 has one deadly bug: when you try to remove a keyword, the app crashes.
In addition, the keyword took is still very weak compared to what Lightroom has and even the dying Aperture software.
Lightroom 1 had the metadata brush. Is this so hard to at least imitate a good idea?
And when you click an image, have the cursor in the keyword field so you don't have to click and then write. Which means taking your stylus and clicking, and then putting the stylus down again to use the keyboard.
A bit more practical sense for UI design, please.
The fact the cursor would be in the keyword field should not prevent from just clicking the already existing keywords...
