It's very painful to search a component when the haystack is composed of hundreds and hundreds of ETL component. So a simple researchbar to search component by name could be great. And to go further a research bar with filter by category (for example : only transform, only table view, only extract and transform, ...). To go more further than this you can add a research bar that recognize functions(those ones in a fieldtransform), and for example if there is a function called "convert_int" in a fieldtransform called "t_ft_conv" if we type on the research bar : 'convert' and we activate the filtre on 'function' the research bar will find the "t_ft_conv". Or searching functions by type like : I want to get all etl component with a groovy functions or a SWITCH functions, I can get them :) !
And add a filter to see which component has an error.
