Gliffy

Ability to be used as an extension within the other document curation tools like Chalk and all within the browser.
Nicely organized set of really good and relevant pre-defined components that really helps quickly drawing an idea into a diagram.

At times, the components become a little bit shaky that they do not behave exactly as they should. Some times memory consumptions becomes a little too heavy for a browser to handle especially for large diagrams.

Chrome app so it's light weight and easy to install. Good balance of features on the free version. Doesn't try to do too much in terms of icons and options - it's the perfect tool if you want to do a process diagram and UML document.

Could benefit from more options with connectors (arrows or direction of flow). The text placement on the diagram elements are not always ideal and can cut off other parts of the diagram. Better file management.

Not much but, I like couple of things like the option from the left panel to add more shapes. This is really a good addition to the tool and the expand and collapse of the left panel is great feature. When we want a room to work on the board we can collapse the left panel and expand it when ever it's required. along with that the resource option which is there in the bottom right corner also a good feature. When there is a new feature enabled, we can have a quick glance to check from there.

The connector tool has a wired behavior some times. After adding the shape, I am not able to add the connectors. I have to click on some other shape in the left pane and then I need to re-select the connectors. This is really frustrating some time. Also the free/trial version if they can share all the features or more features, users can check it out and evaluate the product if they can use it or not, instead of go for a paid version to check all the features.
