IMPORTANT: This is an alpha release (what's this?). Some features may not be complete and there will probably be bugs!
You must be already running 2.3.1.alpha1.
This new feature lets you check your feed items for items of interest and highlight them using different colors or icons. As usual, these can be set globally (from the Display page of the Program Options) or for individual channels.
Specify what you want to look for and if it is a regular expression or not. If it's not a regular expression, Awasu will match any word from what you type e.g. Tom Jones will match any feed item that contains the words Tom or Jones. Use double-quotes if you want to search for "Tom Jones" as a single phrase.
You must also specify where you want to search, either one of the locations in the dropdown list or you can enter the name of any metadata value. This latter feature is very powerful and lets you check for any metadata embedded in your feed items, even if doesn't appear in the title or description. For example, you can look for items authored by your boss and highlight them in red. Or if you are subscribed to corporate internal feeds that embed specialized metadata (e.g. Assigned-To or Priority), you can pick out this information and highlight them as well.
You can find out more about how item metadata works here.
Building on the optimizations already added in alpha1, another one has been implemented that should also speed things up and make the UI even more responsive.
However, nothing comes for free and there is a very small chance of a database corruption if Windows crashes or the power goes off at just the wrong instant. If this is an issue for you, this optimization can be turned off by unchecking Fast database access in the Archive page of the Program Options.
