Hi Tomoki. The ideas page is generally intended for enhancement suggestions for Studio, and whilst we do have ownership of some apps this is not one of them so any enhancements would have to be made through the developer. The best place to raise this is either through a dedicated support contact if there is one on the appstore page for the app, or through the appstore forum in this community - https://community.sdl.com/product-groups/translationproductivity/f/160 The work won't be looked at by the Studio product team.
Nevertheless you are comparing recognition features (in the TM) with the ability to work with content in a bilingual file. Definitley a good idea and probably not trivial since the app can work without a TM being present at all, and you'd need this to be able to take advantage of the TM recognition features provided by Studio.
