TrailRunner

TrailRunner 1.1 features an improved diary. In short it's about search, flag and compare.

Chart
In the new toolbar, switch the area above the entries table to display either calendar based data entry fields or a comparison chart.
The chart reflects the current selection in the diary table, displaying at least 10 weeks from the newest selected entry backwards. If you select more entries in the table, the cart will update to the new entries range.
Entries will always display as a grouped value based on the current interval. The base interval is by weeks and can extend to months if you select a big amount of entries.
In the legend on the right you see the overall values for the displayed data. If you need to know the data for one data-point, select it and you'll see the specific values in the lower legend.

Fitness
The fitness is a calculated value based on pace and heart-rate. The main idea is that if you where very fast with a low heart-rate, you're fitter. In the opposite if you where very slow and had a high heart-rate, you're less. This value is just an orientation and does not have the accuracy of the methods used in Polar watches or other bio-medical methods, but it gives a pretty good overall impression.
The scale of the values is in the value range of the polar watches, but that's only a nice coincidence.

Flag
As you are accustomed from Mail.app, entries can now be flagged in the leftmost column. If you start a series of exercises to reach a certain goal, flag the first one. If you had a very nice exercise or competition, flag it.

Search
The search field in the lower right corner will search for diary entries (looks into column route and personal notes) that contain the given search term. The diary table will then only display matching entries.
This provides various ways to tag and filter diary entries, to later compare entries of the same class. Some examples:
To find out how many kilometers you have accomplished with a pair of shoes, tag all entries with a unique tag like xasc06 (your Asics 2006 pair). When you later search for that term the chart legend will display the values you want to know: number of units and sum of kilometers.
To compare your performance in a certain route over time, enter the routes name and the chart will display the performance values.
To make a distinction between running and biking, tag all runs with xrun and all biking exercises with xmtb. Later search for either tag to see a chart with values only of this kind.
If you use a polar watch and regularly measure your OwnIndex, enter the OwnIndex in the personal comment like ownindex:52. Later search for ownindex and see you progress on the measure checkpoints (unfortunately not in the chart but filtered on entries with this information)

Export
Not a new feature but a good place to mention, if you select diary entries, edit > copy will put them as tab separated columns into the clipboard. An easy method to transfer entries into Excel or other analysis tools.
